This patch fills the net_device vlan_features with the proper hardware features,
thus, improving the vlan interface performance.
With the patch applied, I can see around 148% improvement on a TCP_STREAM test,
from 3.5 Gb/s to 8.7 Gb/s. On TCP_RR, I see a 11% improvement, from 18k
to 20. The CPU utilization is almost the same on both cases, from the comparison
above.

Currently the mlx4 drivers don't have the necessary callbacks to
implement EEH errors detection and recovery, so the PCI layer uses the
probe and remove callbacks to try to recover the device after an error on
the bus. However, these callbacks have race conditions with the internal
catastrophic error recovery functions, which will also detect the error
and this can cause the system to crash if both EEH and catas functions
try to reset the device.
This patch adds the necessary error recovery callbacks and makes sure
that the internal catastrophic error functions will not try to reset the
device in such scenarios. It also adds some calls to
pci_channel_offline() to suppress reads/writes on the bus when the slot
cannot accept I/O operations so we prevent unnecessary accesses to the
bus and speed up the device removal.

The 57840 boards come in two flavours: 2 x 20G and 4 x 10G.
To better differentiate between the two flavours, a separate device ID
was assigned to each.
The silicon default value is still the currently supported 57840 device ID
(0x168d), and since a user can damage the nvram (e.g., 'ethtool -E')
the driver will still support this device ID to allow the user to amend the
nvram back into a supported configuration.

Do RAR entry accounting correctly so that errors are reported and
promisc mode is set correctly when the number of entries exceeds
the hardware limits.
This can happen with many macvlan devices attached to the PF or
by adding many fdb entries in SR-IOV modes.
Also this includes a small refactor to fdb_add() to avoid having so
many nested if/else statements after adding a check for the number
or RAR entries.
The max entries for the PF is currently 16 we allow 15 additional

This change makes it so the function ixgbe_dcb_get_tc_from_up will use the
num_tcs.pg_tcs to determine the starting value for determining a traffic
class based on a user priority. The main motivation for this change is to
address possible bad configurations in which more TCs worth of data are
populated then there are actual TCs. By limiting this value we can at
least make certain we are not providing a map with values that are out of
range.
As a result any user priorities that are setup in the configuration with a
traffic class mapping higher than what the hardware supports will be
reported as being on TC 0.

The recent changes to netdev_alloc_skb actually make it so that the size of
the buffer now actually has a more direct input on the truesize. So in
order to make best use of the piece of a page we are allocated I am
reducing the IXGBE_RX_HDR_SIZE to 256 so that our truesize will be reduced
by 256 bytes as well.
This should result in performance improvements since the number of uses per
page should increase from 4 to 6 in the case of a 4K page. In addition we
should see socket performance improvements due to the truesize dropping
to less than 1K for buffers less than 256 bytes.

This change makes it so that we can use the atr_sample_rate to determine if
we are capable of supporting ATR. The advantage to this approach is that it
allows us to now determine the setting of the IXGBE_FLAG_FDIR_HASH_CAPABLE
based on the queueing scheme, instead of the queueing scheme being based on
the flag.
Using this approach there are essentially 5 conditions that must be checked
prior to trying to enable ATR:
1. Is SR-IOV disabled?
2. Are the number of TCs <= 1?
3. Is RSS queueing limit greater than 1?
4. Is atr_sample_rate set?
5. Is Flow Director perfect filtering disabled?
If any of these conditions are enabled they should disable ATR filtering.
Note that in the case of conditions 1 through 4 being met we will set
things up for ATR queueing, however if test 5 fails we will still leave the
queues allocated for use by perfect filters. The reason for this is to
allow for us to switch back and forth between ntuple and ATR without
needing to reallocate the descriptor rings.

This patch does two things. First it drops the unnecessary work of
searching for enabled VFs when we first bring up the adapter and instead
just uses pci_num_vf to determine how many VFs are enabled on the adapter.
The second thing it does is drop the use of vfdev from the vf_data_storage
structure. Instead we just search the entire system for a VF that has us
as it's PF, and then if that VF is assigned we indicate that the VFs are
assigned. This allows us to still check for assigned VFs even if the
vfinfo allocation has failed, or vfinfo has been freed.

Instead of only setting the FCOE segmentation offload and CRC offload flags
if we enable FCoE, we could just set them always since there are no
modifications needed to the hardware or adapter FCoE structure in order to
use these features.
The advantage to this is that if FCoE enablement fails, for example because
SR-IOV was enabled on 82599, we will still have use of the FCoE
segmentation offload and Tx/Rx CRC offloads which should still help to
improve the FCoE performance.

The current logic is enabling anti-spoof on all pools and then clearing
anti-spoof on just the first PF pool. The correct approach is to only set

This patch changes the behavior of the FCoE configuration so that it is
much closer to how the main body of the ixgbe driver works for ring
allocation.
The first piece is the ixgbe_fcoe_ddp_enable/disable calls. These allocate
the percpu values and if successful set the fcoe_ddp_xid value indicating
that we can support DDP.
The next piece is the ixgbe_setup/free_ddp_resources calls. These are
called on open/close and will allocate and free the DMA pools.
Finally ixgbe_configure_fcoe is now just register configuration. It can go
through and enable the registers for the FCoE redirection offload, and FIP
configuration without any interference from the DDP pool allocation.
The net result of all this is two fold. First it adds a certain amount of
exception handling. So for example if ixgbe_setup_fcoe_resources fails we
will actually generate an error in open and refuse to bring up the
interface.
Secondly it provides a much more graceful failure case than the previous
model which would skip setting up the registers for FCoE on failure to
allocate DDP resources leaving no Rx functionality enabled instead of just
disabling DDP.

This change merges the 2 statistics values for noddp and noddp_ext_buff
and the dma_pool into a single structure that can be allocated per CPU.
The advantages to this are several fold. First we only need to do one
alloc_percpu call now instead of 3, so that means less overhead for
handling memory allocation failures. Secondly in the case of
ixgbe_fcoe_ddp_setup we only need to call get_cpu once which makes things a
bit cleaner since we can drop a put_cpu() from the exception path.

In its receive path, mlx4_en driver maps each page chunk that it pushes
to the hardware and unmaps it when pushing it up the stack. This limits
throughput to about 3Gbps on a Power7 8-core machine.
One solution is to map the entire allocated page at once. However, this
requires that we keep track of every page fragment we give to a
descriptor. We also need to work with the discipline that all fragments will
be released (in the sense that it will not be reused by the driver
anymore) in the order they are allocated to the driver.
This requires that we don't reuse any fragments, every single one of
them must be reallocated. We do that by releasing all the fragments that
are processed and only after finished processing the descriptors, we
start the refill.
We also must somehow guarantee that we either refill all fragments in a
descriptor or none at all, without resorting to giving up a page
fragment that we would have already given. Otherwise, we would break the
discipline of only releasing the fragments in the order they were
allocated.
This has passed page allocation fault injections (restricted to the
driver by using required-start and required-end) and device hotplug
while 16 TCP streams were able to deliver more than 9Gbps.

commit 9ac32e1b firmware: convert e100 driver to request_firmware()
did a straight conversion of the in-driver ucode to external
files. This introduced the possibility of the driver failing
to enable an interface due to missing ucode. There was no
evaluation of the importance of the ucode at the time.
Based on comments in earlier versions of this driver, and in
the source code for the FreeBSD fxp driver, we can assume that
the ucode implements the "CPU Cycle Saver" feature on supported
adapters. Although generally wanted, this is an optional
feature. The ucode source is not available, preventing it from
being included in free distributions. This creates unnecessary
problems for the end users. Doing a network install based on a
free distribution installer requires the user to download and
insert the ucode into the installer.
Making the ucode optional when possible improves the user
experience and driver usability.
The ucode for some adapters include a bugfix, making it
essential. We continue to fail for these adapters unless the
ucode is available.

Use RFS infrastructure and flow steering in HW to keep CPU
affinity of rx interrupts and application per TCP stream.
A flow steering filter is added to the HW whenever the RFS
ndo callback is invoked by core networking code.
Because the invocation takes place in interrupt context, the
actual setup of HW is done using workqueue. Whenever new filter
is added, the driver checks for expiry of existing filters.
Since there's window in time between the point where the core
RFS code invoked the ndo callback, to the point where the HW
is configured from the workqueue context, the 2nd, 3rd etc
packets from that stream will cause the net core to invoke
the callback again and again.
To prevent inefficient/double configuration of the HW, the filters
are kept in a database which is indexed using hash function to enable
fast access.

that we can just access the tx/rx_ring_count values instead of attempting
to access the rings to get the count.
This change corrects a memory leak and memory corruption in

The memory leak was due to us not freeing the resources from the ring
before overwriting them. This change corrects the memory leak by making
certain to call ixgbe_free_tx/rx_resources on the rings prior to freeing
them.
The memory corruption was because we were replacing the rings but not

This change is meant to make the code much more readable for MTQC and MRQC

The big change is that I simplified much of the logic so that we are
essentially handling just 4 cases and their variants. In the cases where
RSS is disabled we are actually just programming the RETA table with all
1s resulting in a single queue RSS. In the case of SR-IOV I am treating
that as a subset of VMDq. This all results int he following configuration

This change cleans up some of the logic in an attempt to try and simplify
things for how we are configuring DCB w/ RSS.
In this patch I basically did 3 things. I updated the logic for getting
the first register index. I applied the fact that all TCs get the same
number of queues to simplify the looping logic in caching the DCB ring
register. Finally I updated how we configure the RQTC register to match
the fact that all TCs are assigned the same number of queues.

Currently VF queues and drivers may remain active during this test.
This could cause memory corruption or spurious test failures.
Therefore we reset the port/function before running these tests on
Siena.
On Falcon this doesn't work: we have to do some additional
initialisation before some blocks will work again. So refactor the
reset/register-test sequence into an efx_nic_type method so
efx_selftest() doesn't have to consider such quirks.
In the process, fix another minor bug: Siena does not have an
'invisible' reset and the self-test currently fails to push the PHY
configuration after resetting. Passing RESET_TYPE_ALL to
efx_reset_{down,up}() fixes this.

Occasionally, the PHY can be initially inaccessible when the first read of

counter similar to how it is done in the generic e1000_get_phy_id().
Also, when the PHY is completely inaccessible (i.e. when subsequent reads
of the PHY_IDx registers returns all F's) and the MDIO access mode must be
set to slow before attempting to read the PHY ID again, the functions that
do these latter two actions expect the SW/FW/HW semaphore is not already
set so the semaphore must be released before and re-acquired after calling
them otherwise there is an unnecessarily inordinate amount of delay during
device initialization.

A number of older ColdFire CPU based boards use NS8390 based network
controllers. Most use the Davicom 9008F or the UMC 9008F. This driver
provides the support code to get these devices working on these platforms.
Generally the NS8390 based eth device is direct connected via the general
purpose bus of the ColdFire CPU. So its addressing and interrupt setup is
fixed on each of the different platforms (classic platform setup).
This driver is based on the other drivers/net/ethernet/8390 drivers, and
includes the lib8390.c code. It uses the existing definitions of the
board NS8390 device addresses, interrupts and access types from the
arch/m68k/include/asm/mcf8390.h, but moves the IO access functions into
the driver code and out of that header.

To allow easy paravirtualization of P_Key and GID table sizes, keep
paravirtualized sizes in mlx4_dev->caps, but save the actual physical
sizes from FW in struct: mlx4_dev->phys_cap.
In addition, in SR-IOV mode, do the following:
1. Reduce reported P_Key table size by 1.
This is done to reserve the highest P_Key index for internal use,
for declaring an invalid P_Key in P_Key paravirtualization.
We require a P_Key index which always contain an invalid P_Key
value for this purpose (i.e., one which cannot be modified by
the subnet manager). The way to do this is to reduce the
P_Key table size reported to the subnet manager by 1, so that
it will not attempt to access the P_Key at index #127.
2. Paravirtualize the GID table size to 1. Thus, each guest sees
only a single GID (at its paravirtualized index 0).
In addition, since we are paravirtualizing the GID table size to 1, we
add paravirtualization of the master GID event here (i.e., we do not
do ib_dispatch_event() for the GUID change event on the master, since
its (only) GUID never changes).

Modify mlx4_dev_cap to allow IB support when SR-IOV is active. Modify
mlx4_slave_cap to set the "rdma-supported" bit in its flags area, and
pass that to the guests (this is done in QUERY_FUNC_CAP and its
wrapper).
However, we don't activate IB support quite yet -- we leave the error
return at the start of mlx4_ib_add in the mlx4_ib driver.
In addition, set "protected fmr supported" bit to zero in the
QUERY_FUNC_CAP wrapper.
Finally, in the QUERY_FUNC_CAP wrapper, we needed to add code which
checks for the port type (IB or Ethernet). Previously, this was not
an issue, since only Ethernet ports were supported.

The SR-IOV special QP tunneling mechanism uses proxy special QPs
(instead of the real special QPs) for MADs on guests. These proxy QPs
send their packets to a "tunnel" QP owned by the master. The master
then forwards the MAD (after any required paravirtualization) to the
real special QP, which sends out the MAD.
For security reasons (i.e., to prevent guests from sending MADs to
tunnel QPs belonging to other guests), each proxy-tunnel QP pair is
assigned a unique, reserved, Q_Key. These Q_Keys are available only
for proxy and tunnel QPs -- if the guest tries to use these Q_Keys
with other QPs, it will fail.
This patch introduces a mechanism for reserving a block of 64K Q_Keys
for proxy/tunneling use.
The patch introduces also two new fields into mlx4_dev: base_sqpn and
base_tunnel_sqpn.
In SR-IOV mode, the QP numbers for the "real," proxy, and tunnel sqps
are added to the reserved QPN area (so that they will not change).
There are 8 special QPs per port in the HCA, and each of them is
assigned both a proxy and a tunnel QP, for each VF and for the PF as
well in SR-IOV mode.
The QPNs for these QPs are arranged as follows:
1. The real SQP numbers (8)
2. The proxy SQPs (8 * (max number of VFs + max number of PFs)
3. The tunnel SQPs (8 * (max number of VFs + max number of PFs)
To support these QPs, two new fields are added to struct mlx4_dev:
base_sqp: this is the QP number of the first of the real SQPs
base_tunnel_sqp: this is the qp number of the first qp in the tunnel
sqp region. (On guests, this is the first tunnel
sqp of the 8 which are assigned to that guest).
In addition, in SR-IOV mode, sqp_start is the number of the first
proxy SQP in the proxy SQP region. (In guests, this is the first
proxy SQP of the 8 which are assigned to that guest)
Note that in non-SR-IOV mode, there are no proxies and no tunnels.
In this case, sqp_start is set to sqp_base -- which minimizes code
changes.

The port management change event can replace smp_snoop. If the
capability bit for this event is set in dev-caps, the event is used
(by the driver setting the PORT_MNG_CHG_EVENT bit in the async event
mask in the MAP_EQ fw command). In this case, when the driver passes
incoming SMP PORT_INFO SET mads to the FW, the FW generates port
management change events to signal any changes to the driver.
If the FW generates these events, smp_snoop shouldn't be invoked in
ib_process_mad(), or duplicate events will occur (once from the
FW-generated event, and once from smp_snoop).
In the case where the FW does not generate port management change
events smp_snoop needs to be invoked to create these events. The flow
in smp_snoop has been modified to make use of the same procedures as
in the fw-generated-event event case to generate the port management
events (LID change, Client-rereg, Pkey change, and/or GID change).
Port management change event handling required changing the
mlx4_ib_event and mlx4_dispatch_event prototypes; the "param" argument
(last argument) had to be changed to unsigned long in order to
accomodate passing the EQE pointer.
We also needed to move the definition of struct mlx4_eqe from
net/mlx4.h to file device.h -- to make it available to the IB driver,
to handle port management change events.

For RTL8111G, the settings of phy and firmware are replaced with
ocp functions. r8168g_mdio_{write / read} redirects the relative
settings to suitable ocp functions. A per-device variable is needed
to evaluate the real address of ocp functions.
rtl_writephy(tp, 0x1f, xxxx) is dedicated to keeping said variable
up-to-date.

For the higher mtu sizes requiring the buffer size greater than 8192,
the buffers are sent or received using multiple dma descriptors/ same
descriptor with option of multi buffer handling.
It was observed during tests that the driver was missing on data
packets during the normal ping operations if the data buffers being used
catered to jumbo frame handling.
The memory barrriers are added in between preparation of dma descriptors
in the jumbo frame handling path to ensure all instructions before
enabling the dma are complete.

It was observed that during multiple reboots nfs hangs. The status of
receive descriptors shows that all the descriptors were in control of
CPU, and none were assigned to DMA.
Also the DMA status register confirmed that the Rx buffer is
unavailable.
This patch adds the fix for the same by adding the memory barriers to
ascertain that the all instructions before enabling the Rx or Tx DMA are
completed which involves the proper setting of the ownership bit in DMA
descriptors.

DCB and SR-IOV cannot currently be enabled at the same time as the queueing
schemes are incompatible. If they are both enabled it will result in Tx
hangs since only the first Tx queue will be able to transmit any traffic.
This simple fix for this is to block us from enabling TCs in ixgbe_setup_tc
if SR-IOV is enabled. This change will be reverted once we can support
SR-IOV and DCB coexistence.

commit a1c7fff7e1 (net: netdev_alloc_skb() use build_skb()) broke b44 on
some 64bit machines.
It appears b44 and b43 use __netdev_alloc_skb() instead of alloc_skb()
for their bounce buffers.
There is no need to add an extra NET_SKB_PAD reservation for bounce
buffers :
- In TX path, NET_SKB_PAD is useless
- In RX path in b44, we force a copy of incoming frames if
GFP_DMA allocations were needed.

The drop action is implemented by allocating a QP and keeping it in a reset state
such that the HW drops any packets which are steered to that QP. When a drop action

The device managed flow steering API has three promiscuous modes:
1. Uplink - captures all the packets that arrive to the port.
2. Allmulti - captures all multicast packets arriving to the port.
3. Function port - for future use, this mode is not implemented yet.
Use these modes with the flow_attach and flow_detach firmware commands
according to the promiscuous state of the netdevice.

The driver is modified to support three operation modes.
If supported by firmware use the device managed flow steering
API, that which we call device managed steering mode. Else, if
the firmware supports the B0 steering mode use it, and finally,
if none of the above, use the A0 steering mode.
When the steering mode is device managed, the code is modified
such that L2 based rules set by the mlx4_en driver for Ethernet
unicast and multicast, and the IB stack multicast attach calls
done through the mlx4_ib driver are all routed to use the device
managed API.
When attaching rule using device managed flow steering API,
the firmware returns a 64 bit registration id, which is to be
provided during detach.
Currently the firmware is always programmed during HCA initialization
to use standard L2 hashing. Future work should be done to allow
configuring the flow-steering hash function with common, non
proprietary means.

Instead of checking the firmware supported steering mode in various
places in the code, add a dedicated field in the mlx4 device capabilities
structure which is written once during the initialization flow and read
across the code.
This also set the grounds for add new steering modes. Currently two modes
are supported, and are named after the ConnectX HW versions A0 and B0.
A0 steering uses mac_index, vlan_index and priority to steer traffic
into pre-defined range of QPs.
B0 steering uses Ethernet L2 hashing rules and is enabled only
if the firmware supports both unicast and multicast B0 steering,
The current steering modes are relevant for Ethernet traffic only,
such that Infiniband steering remains untouched.

Currently, for every change in the net device multicast list, the driver
detaches all the addresses from the HW device, and then attaches the
updated list. This behavior is wrong from two aspects: first, it causes
a load of firmware commands and second, there is period of time where
the correct addresses are not attached, which turned into packet loss.
To improve - a copy of the multicast list is saved by the driver. For
every change in the multicast list, the multicast list copy is used
to find the delta between those two lists and add or remove multicast
addresses as needed.
