fc51de96ed i40e: Only enable TC0 for NIC partition type
In case of MFP mode the driver was returning incorrect number of TCs
for partitions that are not enabled for iSCSI. Though the driver does
not configure these TCs in the Tx scheduler for the NIC partitions;
it does use this map to setup the queue mappings.

This patch fixes this and keeps all the NIC partitions to the default
PF TC i.e. TC0.

66ddcffb1a i40e: Fix RSS size at init since default num queue calculation has changed
With changes to default number of queue pairs that the interface comes up with
from 1 per online CPU to 1 per lan_msix, we need to make sure we recalculate
rss_size. We will now recalculate rss_size based on number of queues enabled in
the VSI.

Without this fix if the max_lan_msix < num_online_cpu we will be coming up
with fewer queues but will be populating rss_size based on num_online_cpus.
This will result in packets getting silently dropped because RSS LUT has queues
that are not enabled.

prevent the driver from attempting to feed a header to the hardware too

the inner L4 header length based on whether it is TCP or UDP.

dacc73e0cf sh_eth: Really fix padding of short frames on TX
My previous fix to clear padding of short frames used skb->len as the
DMA length, assuming that skb_padto() extended skb->len to include the
padding.  That isn't the case; we need to use skb_put_padto() instead.

(This wasn't immediately obvious because software padding isn't
actually needed on the R-Car H2.  We could make it conditional on
which chip is being driven, but it's probably not worth the effort.)

This reverts commit fd9af07c34.

The hardware manual states that the frame error and multicast bits are
copied to bits 9:0 of RD0, not bits 25:16.  I've tested that this is
true for RFS1 (CRC error), RFS3 (frame too short), RFS4 (frame too
long) and RFS8 (multicast).

Also adjust a comment to agree with this.

6ded286555 sh_eth: Fix RX recovery on R-Car in case of RX ring underrun
In case of RX ring underrun (RDE), we attempt to reset the software
descriptor pointers (dirty_rx and cur_rx) to match where the hardware
will read the next descriptor from, as that might not be the first
dirty descriptor.  This relies on reading RDFAR, but that register
doesn't exist on all supported chips - specifically, not on the R-Car
chips.  This will result in unpredictable behaviour on those chips
after an RDE.

Make this pointer reset conditional and assume that it isn't needed on
the R-Car chips.  This fix also assumes that RDFAR is never exposed at
offset 0 in the memory map - this is currently true, and a subsequent
commit will fix the ambiguity between offset 0 and no-offset in the
register offset maps.

Most of the time, the issues we want to debug with the

hard to stop the recording on time and get meaningful
data.
In order to solve this, I add here an infrastucture
of triggers. The user will supply a list of triggers
that will start / stop the recording. We have two types
of triggers: start and stop. Start triggers can start a
specific configuration. The stop triggers will be able to
kick the collection of the data with the currently running
configuration. These triggers are given to the driver by
the .ucode file - just like the configuration.

In the next patches, I'll add triggers in the code.

e0ede17789 iwlwifi: mvm: don't iterate interfaces to disconnect in net-detect
We shouldn't call iwl_mvm_d3_disconnect_iter() on the running
interfaces when we are woken up due to net-detect, because it doesn't
make sense.  Additionally, this seems to set the
IEEE80211_SDATA_DISCONNECT_RESUME flag that will cause a disconnection
on the next resume (if a normal WoWLAN is used).

To solve this, skip the iteration loop when net-detect is set.

287f3a943f pppoe: Use workqueue to die properly when a PADT is received
When a PADT frame is received, the socket may not be in a good state to
close down the PPP interface. The current implementation handles this by
simply blocking all further PPP traffic, and hoping that the lack of traffic
will trigger the user to investigate.

Use schedule_work to get to a process context from which we clear down the
PPP interface, in a fashion analogous to hangup on a TTY-based PPP
interface. This causes pppd to disconnect immediately, and allows tools to
take immediate corrective action.

Note that pppd's rp_pppoe.so plugin has code in it to disable the session
when it disconnects; however, as a consequence of this patch, the session is
already disabled before rp_pppoe.so is asked to disable the session. The
result is a harmless error message:

Failed to disconnect PPPoE socket: 114 Operation already in progress

This message is safe to ignore, as long as the error is 114 Operation
already in progress; in that specific case, it means that the PPPoE session
has already been disabled before pppd tried to disable it.

Commit 740c7f31c0 ("sh_eth: Ensure DMA engines are stopped before
freeing buffers") added a call to sh_eth_reset() to the
sh_eth_set_ringparam() and sh_eth_close() paths.

However, setting the software reset bit(s) in the EDMR register resets
the MAC Address Registers to zero. Hence after kexec, the new kernel
doesn't detect a valid MAC address and assigns a random MAC address,
breaking DHCP.

Set the MAC address again after the reset in sh_eth_dev_exit() to fix
this.

Tested on r8a7740/armadillo (GETHER) and r8a7791/koelsch (FAST_RCAR).

2f1d8b9e8a macvtap: make sure neighbour code can push ethernet header
Brian reported crashes using IPv6 traffic with macvtap/veth combo.

I tracked the crashes in neigh_hh_output()

-> memcpy(skb->data - HH_DATA_MOD, hh->hh_data, HH_DATA_MOD);

Neighbour code assumes headroom to push Ethernet header is
at least 16 bytes.

It appears macvtap has only 14 bytes available on arches
where NET_IP_ALIGN is 0 (like x86)

Effect is a corruption of 2 bytes right before skb->head,
and possible crashes if accessing non existing memory.

This fix should also increase IPv4 performance, as paranoid code
in ip_finish_output2() wont have to call skb_realloc_headroom()

59995370db hyperv: Implement netvsc_get_channels() ethool op
This adds support for reporting the actual and maximum combined channels
count of the hv_netvsc driver via 'ethtool --show-channels'.

This required adding 'max_chn' to 'struct netvsc_device', and assigning
it 'rsscap.num_recv_que' in 'rndis_filter_device_add'. Now we can access
the combined maximum channel count via 'struct netvsc_device' in the
ethtool callback.

5688714977 drivers: net: cpsw: Set SECURE for dual_emac ucast
Prior to this patch, sending a packet with the source MAC address of one
of the CPSW interfaces to one of the CPSW slave ports while it's configured in
dual_emac mode would update the port_num field of the VLAN/Unicast Address
Table Entry. This would cause it to discard all incoming traffic addressed to
that MAC address, essentially rendering the port useless until the ALE table is
cleared (by starting and stopping the interface or rebooting.)

For example, if eth0 has a MAC address of 90:59:af:8f:43:e9 it will have
an ALE table entry:

00 00 00 00 59 90 02 30 e9 43 8f af
(VLAN Addr vlan_id=2 unicast type=0 port_num=0 addr=90:59:af:8f:43:e9)

If you configure another device with the same MAC address and connect it
to the first CPSW slave port and send some traffic the ALE table entry
becomes:

04 00 00 00 59 90 02 30 e9 43 8f af
(VLAN Addr vlan_id=2 unicast type=0 port_num=1 addr=90:59:af:8f:43:e9)

>From this point forward all incoming traffic addressed to
90:59:af:8f:43:e9 will be dropped.

Setting the SECURE bit for the VLAN/Unicast address table entry for each
interface's MAC address corrects the problem.

6588af614e usbnet: Fix tx_packets stat for FLAG_MULTI_FRAME drivers
Currently the usbnet core does not update the tx_packets statistic for
drivers with FLAG_MULTI_PACKET and there is no hook in the TX
completion path where they could do this.

cdc_ncm and dependent drivers are bumping tx_packets stat on the
transmit path while asix and sr9800 aren't updating it at all.

Add a packet count in struct skb_data so these drivers can fill it
in, initialise it to 1 for other drivers, and add the packet count
to the tx_packets statistic on completion.

There is a discrepancy here because the niu_class_to_ethflow() returns
zero on failure and one on success but the caller expected zero on
success and negative on failure.

The problem means that we allow the user to pass classes and flow_types
which we don't want.  I've looked at it a bit and I don't see it as a
very serious bug.

b70661c708 net: smc91x: use run-time configuration on all ARM machines
The smc91x driver traditionally gets configured at compile-time
for whichever hardware it runs on. This no longer works on
ARM as we continue to move to building all-in-one kernels.

Most ARM configurations with this driver already use run-time
configuration through DT or through platform_data, but a
few have not been converted yet.

I've checked all ARM boards that use this driver in their
legacy board files, and converted the ones that were using
compile-time configuration in smc91x.h to behave like the
other ones and provide the interrupt polarity along with
the MMIO configuration (width, stride) at platform device
creation time.

In particular, these combinations were previously selectable
in Kconfig but in fact broken:

- sa1100 assabet plus pleb
- msm combined with any other armv6/v7 platform
- pxa-idp combined with any non-DMA pxa variant
- LogicPD PXA270 combined with any other pxa
- nomadik combined with any other armv4/v5 platform,
  e.g. versatile.

None of these seem critical enough to warrant a backport
to stable, but it would be nice to clean this up for good.

I would like the patch to get merged through netdev, after
Robert and/or Linus have verified it on at least some hardware.

There are a few other non-ARM platforms using this driver,
I could do the same patch for those if we want to take
it further.

061c1a6e36 Merge branch 'master' of git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/net
Jeff Kirsher says:

====================
Intel Wired LAN Driver Updates 2015-02-26

This series contains fixes for i40e and i40evf only.

Alexey Khoroshilov found a possible leak of 'cmd_buf' when copy_from_user()
failed in i40e_dbg_command_write(), so resolved by calling kfree().

Shannon provides a fix to ensure the shift and bitwise precedences do not
work backwards for us by adding parans.  Fixed the driver by preventing
the driver from allowing stray interrupts or causing system logs from
un-handled interrupts by combining the ICR0 shutdown with the standard
interrupt shutdown and add the interrupt clearing to the PCI shutdown
path.  Fixed an issue where a NVM write times out before a transaction
can complete, so Shannon added logic to make another attempt by
reacquiring the semaphore, then retry the write, if the one retry fails,
we will then give up.  Adds checks to pointers before their use to ensure
we do not try to dereference NULL pointers when returning values from the
AdminQ calls.

Akeem adds a check to bail out if the device is already down when checking
for Tx hang subtask.

Anjali fixes TSO with more than 8 frags per segment issue.  The hardware
has some limitations which the driver needs to adhere to:
  1) no more than 8 descriptors per packet on the wire
  2) no header can span more than 3 descriptors
If one of these events happens, the hardware will generate an internal
error and freeze the Tx queue, so Anjali fixes this by linearizes the skb
to avoid these situations.  Fixed an issue where the per Traffic Class
queue count was higher than queues enabled, which will fix a warning
with multiple function mode where systems regularly have more cores than
vectors.  Fixed TCP/IPv6 over VXLAN Tx checksum offload, where we were
checking the outer protocol flags and deciding the flow for the inner
header.

Jesse fixes a race condition in the transmit hang detection.  Before we
were having issues of false Tx hang detection, no the driver makes more
direct with the checks for progress forward by directly checking the head
write back address and tail register when determining progress.  This
avoids Tx hangs where the software gets behind, because we are directly
checking hardware state when determining a hang state.

Neerav fixes the transmit ring Qset handle when DCB reconfigures. The issue
was when DCB is reconfigured to a single traffic class (TC) and the driver
did not reset the Tx ring Qset handle to correct the mapping, which caused
the Tx queue to disable timeouts.  Also as part of DCB reconfiguration flow
if the Tx queue disable times out, then issue a PF reset to do some level
of recovery.

Mitch stops flow director on shutdown because, in some cases, the hardware
would continue to try to access the FDIR ring after entering D3Hot state,
which would cause either PCIe errors or NMIs, depending upon the system
configuration.

* NOTE * I have verified that this series of patches for net will not cause
any merge issues when you sync up your net tree with your net-next tree.

Lendacky, Thomas
c30e76a728 amd-xgbe: Request IRQs only after driver is fully setup
It is possible that the hardware may not have been properly shutdown
before this driver gets control, through use by firmware, for example.
Until the driver is loaded, interrupts associated with the hardware
could go pending. When the IRQs are requested napi support has not
been initialized yet, but the ISR will get control and schedule napi
processing resulting in a kernel panic because the poll routine has not
been set.

Adjust the code so that the driver is fully ready to handle and process
interrupts as soon as the IRQs are requested. This involves requesting
and freeing IRQs during start and stop processing and ordering the napi
add and delete calls appropriately.

Also adjust the powerup and powerdown routines to match the start and
stop routines in regards to the ordering of tasks, including napi
related calls.

04c7b363c9 mwifiex: more_task flag for main_process
This patch handles a corner case where TX packet would remain in
driver queue till next packet comes in.
Here is sequence:
1. TX packet is queued via hard_start_xmit and main_work is queued
2. SDIO interrupt comes in which directly call mwifiex_main_process.
This starts executing main superloop.
3. Now work from step1 is scheduled but at first check itself it sees
mwifiex_processing is set and exits.
4. Now if superloop from step2 has passed TX processing part of superloop
this packet would remain in queue until next packet/command/SDIO interrupt
arrives and queues main_work.

This patch fixes this corner case by defining more_task flag which is set when
mwifiex_processing is found to be true. At end of superloop we again check if
more_task flag is set and if set, execute superloop again.

e47172ab7e rocker: put port in FORWADING state after leaving bridge
Cleanup the port forwarding state transitions for the cases when the port
joins or leaves a bridge, or is brought admin UP or DOWN.  When port is
bridged, we can rely on bridge driver putting port in correct state using
STP callback into port driver, regardless if bridge is enabled for STP or not.
When port is not bridged, we can reuse some of the STP code to enabled or
disable forwarding depending on UP or DOWN.

Tested by trying all the transitions from bridge/not bridge, and UP/DOWN, and
verifying port is in the correct forwarding state after each transition.

4a6bb6d359 rocker: rename lport to pport
This is just a rename of physical ports from "lport" to "pport".  Not a
functional change.  OF-DPA uses logical ports (lport) for tunnels, but the
driver (and device) were using "lport" for physical ports.  Renaming physical
ports references to "pport", freeing up "lport" for use later with tunnels.

7eb344f873 rocker: fix non-portable err return codes
The rocker device returns error codes if something goes wrong with descriptor
processing.  Originally the device used standard errno codes for different
errors, but since those errno codes aren't portable across ARCHs, the device
now returns hard-coded error codes that stay constant across diff ARCHs.  Fix
driver to use those same hard-coded values.
