On packet RX, we perform a dma sync for cpu before passing the
packet up. Here we limit that sync to the actual length of the
incoming packet, rather than always syncing the entire buffer.

Multiple IES API resets can cause a race condition where the mailbox
interrupt request bits can be cleared before being handled. This can
leave certain mailbox messages from the PF to be untreated and the PF
will enter in some inactive state. If this situation occurs, the IES API
will initiate a mailbox version reset which, then, trigger a mailbox
state change. Once this mailbox transition occurs (from OPEN to CONNECT
state), a request for reset will be returned.
This ensures that PF will undergo a reset whenever IES API encounters an
unknown global mailbox interrupt event or whenever the IES API
terminates.

Here is an implementation of an allocator that allocates blue flame
registers. A blue flame register is used for generating send doorbells.
A blue flame register can be used to generate either a regular doorbell
or a blue flame doorbell where the data to be sent is written to the
device's I/O memory hence saving the need to read the data from memory.
For blue flame kind of doorbells to succeed, the blue flame register
need to be mapped as write combining. The user can specify what kind of
send doorbells she wishes to use. If she requested write combining
mapping but that failed, the allocator will fall back to non write
combining mapping and will indicate that to the user.
Subsequent patches in this series will make use of this allocator.

ALE h/w on newer version of NetCP (K2E/L/G) does provide a ALE_STATUS
register for the size of the ALE Table implemented in h/w. Currently
for example we set ALE Table size to 1024 for NetCP ALE on
K2E even though the ALE Status/Documentation shows it has 8192 entries.
So take advantage of this register to read the size of ALE table supported
and use that value in the driver for the newer version of NetCP ALE.
For NetCP lite, ALE Table size is much less (64) and indicated by a size
of zero in ALE_STATUS. So use that as a default for now. While at it,
also fix the ale table size on 10G switch to 2048 per User guide

In NU Ethernet switch used on some of the Keystone SoCs, there is
separate UNKNOWNVLAN register for membership, unreg mcast flood, reg
mcast flood and force untag egress bits in ALE. So control for these
fields require different address offset, shift and size of field.
As this ALE has the same version number as ALE in CPSW found on other
SoCs, customization based on version number is not possible. So
use a configuration parameter, nu_switch_ale, to identify the ALE
ALE found in NU Switch. Different treatment is needed for NU Switch
ALE due to difference in the ale table bits, separate unknown vlan
registers etc. The register information available in ale_controls,
needs to be updated to support the netcp NU switch h/w. So it is not
constant array any more since it needs to be updated based
on ALE type. The header of the file is also updated to indicate it
supports N port switch ALE, not just 3 port. The version mask is
3 bits in NU Switch ALE vs 8 bits on other ALE types.
While at it, change the debug print to info print so that ALE
version gets displayed in boot log.

The CPDMA uses one pool of descriptors for both RX and TX which by default
split between all channels proportionally depending on total number of
CPDMA channels and number of TX and RX channels. As result, more
descriptors will be consumed by TX path if there are more TX channels and
there is no way now to dedicate more descriptors for RX path.
So, add the ability to re-split CPDMA pool of descriptors between RX and TX
path via ethtool '-G' command wich will allow to configure and fix number
of descriptors used by RX and TX path, which, then, will be split between
RX/TX channels proportionally depending on RX/TX channels number and
weight. ethtool '-G' command will accept only number of RX entries and rest
of descriptors will be arranged for TX automatically.
Command:
ethtool -G <devname> rx <number of descriptors>
defaults and limitations:
- minimum number of rx descriptors is 10% of total number of descriptors in
CPDMA pool
- maximum number of rx descriptors is 90% of total number of descriptors in
CPDMA pool
- by default, descriptors will be split equally between RX/TX path
- any values passed in "tx" parameter will be ignored
Usage:
# ethtool -g eth0
Pre-set maximums:
RX: 7372
RX Mini: 0
RX Jumbo: 0
TX: 0
Current hardware settings:
RX: 4096

The CPSW CPDMA can process buffer descriptors placed as in internal
CPPI RAM as in DDR. This patch adds support in CPSW and CPDMA for
descs_pool_size mudule parameter, which defines total number of CPDMA CPPI
descriptors to be used for both ingress/egress packets processing:
- memory size, required for CPDMA descriptor pool, is calculated basing
on number of descriptors specified by user in descs_pool_size and
CPDMA descriptor size and allocated from coherent memory (CMA area);
- CPDMA descriptor pool will be allocated in DDR if pool memory size >
internal CPPI RAM or use internal CPPI RAM otherwise;
- if descs_pool_size not specified in DT - the default value 256 will
be used which will allow to place CPDMA descriptors pool into the
internal CPPI RAM (current default behaviour);
- CPDMA will ignore descs_pool_size if descs_pool_size = 0 for
backward comaptiobility with davinci_emac.
descs_pool_size is boot time setting and can't be changed once
CPSW/CPDMA is initialized.

It's observed that cpsw/cpdma is not working properly when CPPI
descriptors are placed in DDR instead of internal CPPI RAM on am437x
SoC:
- rx/tx silently stops processing packets;
- or - after boot it's working for sometime, but stuck once Network
load is increased (ping is working, but iperf is not).
(The same issue has not been reproduced on am335x and am57xx).
It seems that write to HDP register processed faster by interconnect
than writing of descriptor memory buffer in DDR, which is probably
caused by store buffer / write buffer differences as these functions
are implemented differently across devices. So, to fix this i come up
with two minimal, required changes:
1) all accesses to the channel register HDP/CP/RXFREE registers should
be done using sync IO accessors readl()/writel(), because all previous
memory writes writes have to be completed before starting channel
(write to HDP) or completing desc processing.
2) the change 1 only doesn't work on am437x and additional reading of
desc's field is required right after the new descriptor was filled
with data and before pointer on it will be stored in
prev_desc->hw_next field or HDP register.
In addition, to above changes this patch eliminates all relaxed ordering
I/O accessors in this driver as suggested by David Miller to avoid such
kind of issues in the future, but with one exception - relaxed IO accessors
will still be used to fill desc in cpdma_chan_submit(), which is safe as
there is read barrier at the end of write sequence, and because sync IO
accessors usage here will affect on net performance.

The issue comes when there are multiple threads attempting to use
the mailbox facility at the same time.
When DCB operations and interface up/down is run in a loop for every
0.1 sec, we observed mailbox collisions. And out of the two commands
one would fail with the present code, since we don't queue the second
command.
To overcome the above issue, added a queue to access the mailbox.
Whenever a mailbox command is issued add it to the queue. If its at
the head issue the mailbox command, else wait for the existing command
to complete. Usually command takes less than a milli-second to
complete.
Also timeout from the loop, if the command under execution takes
long time to run.
In reality, the number of mailbox access collisions is going to be
very rare since no one runs such abusive script.

For proper IRQ generation by DP83867 phy the INT/PWDN pin has to be
programmed as an interrupt output instead of a Powerdown input in
Configuration Register 3 (CFG3), Address 0x001E, bit 7 INT_OE = 1. The
current driver doesn't do this and as result IRQs will not be generated by
DP83867 phy even if they are properly configured in DT.
Hence, fix IRQ generation by properly configuring CFG3.INT_OE bit and
ensure that Link Status Change (LINK_STATUS_CHNG_INT) and Auto-Negotiation
Complete (AUTONEG_COMP_INT) interrupt are enabled. After this the DP83867

Whenever the igb driver detects the result of a read operation returns
a value composed only by F's (like 0xFFFFFFFF), it will detach the
net_device, clear the hw_addr pointer and warn to the user that adapter's
link is lost - those steps happen on igb_rd32().
In case a PCI error happens on Power architecture, there's a recovery
mechanism called EEH, that will reset the PCI slot and call driver's
handlers to reset the adapter and network functionality as well.
We observed that once hw_addr is NULL after the error is detected on
igb_rd32(), it's never assigned back, so in the process of resetting
the network functionality we got a NULL pointer dereference in both
igb_configure_tx_ring() and igb_configure_rx_ring(). In order to avoid
such bug, this patch re-assigns the hw_addr value in the slot_reset
handler.

During systemd reboot sequence network driver interface is shutdown
by e1000_close. The PCI driver interface is shut by e1000_shutdown.
The e1000_shutdown checks for netif_running status, if still up it
brings down driver. But it disables msi outside of this if statement,
regardless of netif status. All this is OK when e1000_close happens
after shutdown. However, by default, everything in systemd is done
in parallel. This creates a conditions where e1000_shutdown is called
after e1000_close, therefore hitting BUG_ON assert in free_msi_irqs.

Inserting the TSB means adding an extra 8 bytes in front the of packet
that is going to be used as metadata information by the TDMA engine, but
stripped off, so it does not really help with the packet padding.
For some odd packet sizes that fall below the 60 bytes payload (e.g: ARP)
we can end-up padding them after the TSB insertion, thus making them 64
bytes, but with the TDMA stripping off the first 8 bytes, they could
still be smaller than 64 bytes which is required to ingress the switch.
Fix this by swapping the padding and TSB insertion, guaranteeing that
the packets have the right sizes.

There are two problems with EEPROM access. One is that it needs to
hold the semaphore until the entire response is read or else the
response can be corrupted by other firmware accesses. The second
problem is that acquiring and releasing the semaphore is slow, so
it should be taken and released once when multiple EEPROM accesses
will be done.
Both of these issues can be solved by adding a new function,
ixgbe_hic_unlocked, to issue firmware commands that will assume
that the caller has acquired the needed semaphore.

There are two methods for setting mac addresses in a Macvlan, that
differentiate themselves in the function macvlan_set_mac_Address.
If the macvlan mode is passthru, then we use the dev_set_mac_address
method, otherwise we use the dev_uc api via macvlan_sync_addresses.
The latter method (which would stem from using any non-passthru mode,
like bridge, or vepa), calls down into the driver in a path that terminates
in ixgbevf_set_uc_addr_vf, which sends a IXGBE_VF_SET_MACVLAN message,
which causes the pf to spawn the noted error message. This occurs because
it appears that the guest is trying to delete the mac address of the macvlan
before adding another.
The other path in macvlan_set_mac_address uses dev_set_mac_address, which
calls into ixgbevf_set_mac which uses the IXGBE_VF_SET_MAC_ADDR to the
pf to set the macvlan mac address.
The discrepancy here is in the handlers. The handler function for
IXGBE_VF_SET_MAC_ADDR (ixgbe_set_vf_mac_addr) has a check for
the vfinfo[].trusted bit to allow the operation if the vf is trusted.
In comparison, the IXGBE_VF_SET_MACVLAN message handler
(ixgbe_set_vf_macvlan_msg) has no such check of the trusted bit.

When VXLAN offloading is enabled, be_features_check() tries to check if
an encapsulated packet is indeed a VXLAN packet. The check is not strict
enough, and considers any UDP-encapsulated ethernet frame with a 8-byte
tunnel header as being VXLAN. Unfortunately, both GENEVE and VXLAN-GPE
have a 8-byte header, so they get through this check.
Force the UDP destination port to be the one that has been offloaded to
hardware.
Without this, GENEVE-encapsulated packets can end up having an incorrect
checksum when both a GENEVE and a VXLAN (offloaded) tunnel are
configured.

For core revision 3.x Address-Aligned Beats is available in two registers.
The DT property snps,aal was created for AAL in the DMA bus register,
which is a read/write bit.
The DT property snps,axi_all was created for AXI_AAL in the AXI bus mode
register, which is a read only bit that reflects the value of AAL in the
DMA bus register.
Since the value of snps,axi_all is never used in the driver,
and since the property was created for a bit that is read only,
it should be safe to remove the property.

During Rx flow driver allocates a replacement buffer each time
it consumes an Rx buffer. Failing to do so, it would consume the
currently processed buffer and re-post it on the ring.
As a result, the Rx ring is always completely full [from driver POV].
We now allow the Rx ring to shorten by doing the re-allocations
at the end of the NAPI run. The only limitation is that we still want to
make sure each time we reallocate that we'd still have sufficient
elements in the Rx ring to guarantee that FW would be able to post
additional data and trigger an interrupt.

Today qede requests contexts that would suffice for 64 'whole'
combined queues [192 meant for 64 rx, tx and xdp tx queues],
but registers netdev and limits the number of queues based on
information received by qed. In turn, qed doesn't take context
into account when informing qede how many queues it can support.
This would lead to a configuration problem in case user tries
configuring >64 combined queues to interface [or >96 in case
xdp isn't enabled]. Since we don't have a mangement firware
that actually provides so many interrupt lines to a single
device we're currently safe but that's about to change soon.
The new maximum is hence changed:
- For RoCE devices, the limit would remain 64.
- For non-RoCE devices, the limit might be higher [depending
on the actual configuration of the device].
qed would start enforcing that limit in both scenarios.
