It is possible that the interface is already gone after joining
the list of anycast on this interface as we don't hold a refcount
for the device, in this case we are safe to ignore the error.
What's more important, for API compatibility we should not
change this behavior for applications even if it were correct.

amd-xgbe: AMD XGBE driver fixes 2014-09-05
The following series of patches includes fixes to the driver.
- Proper access to 64 bit management counter registers
- Enable all management counter registers to generate an interrupt when
the counter threshold is reached
This patch series is based on net.
====================
Signed-off-by: David S. Miller <davem@davemloft.net>
As the management counters reach a threshold they will generate an
interrupt so the value can be saved and the counter reset. The
current code does not enable this interrupt on all counters. This
can result in inaccurate statistics.
Update the code to enable all the counters to generate an interrupt
when its threshold is exceeded.
Signed-off-by: Tom Lendacky <thomas.lendacky@amd.com>
Signed-off-by: David S. Miller <davem@davemloft.net>
Even if the management counters are configured to be 32 bit register
values, the [rt]xoctetcount_gb and [rt]xoctetcount_g counters are
always 64 bit counter registers. Since they are not being treated as
64 bit values, these statistics are being reported incorrectly (ifconfig,
ethtool, etc.).
Update the routines used to read the registers to access the "hi"
register (an offset of 4 from the "lo" register) to create a 64 bit
value for these 64 bit counters.

This patch does not affect the 10/100 GRETH MAC.
Before all GBit GRETH TX descriptor ring cleaning was done in
start_xmit(), when descriptor list became full it activated
TX interrupt to start the NAPI rx poll function to do TX ring
cleaning.
With this patch the TX descriptor ring is always cleaned from
the NAPI rx poll function, triggered via TX or RX interrupt.
Otherwise we could end up in TX frames being sent but not
reported to the stack being sent. On the 10/100 GRETH this
is not an issue since the SKB is copied&aligned into private
buffers so that the SKB can be freed directly on start_xmit()

The timestamping API has separate bits for generating and reporting
timestamps. A software timestamp should only be reported for a packet
when the packet has the relevant generation flag (SKBTX_..) set
and the socket has reporting bit SOF_TIMESTAMPING_SOFTWARE set.
The second check was accidentally removed. Reinstitute the original
behavior.
Tested:
Without this patch, Documentation/networking/txtimestamp reports
timestamps regardless of whether SOF_TIMESTAMPING_SOFTWARE is set.
After the patch, it only reports them when the flag is set.

pull request: Netfilter/IPVS fixes for net
The following patchset contains seven Netfilter fixes for your net
tree, they are:
1) Make the NAT infrastructure independent of x_tables, some users are
already starting to test nf_tables with NAT without enabling x_tables.
Without this patch for Kconfig, there's a superfluous dependency
between NAT and x_tables.
2) Allow to use 0 in the cgroup match, the kernel rejects with -EINVAL
with no good reason. From Daniel Borkmann.
3) Select CONFIG_NF_NAT from the nf_tables NAT expression, this also
resolves another NAT dependency with x_tables.
4) Use HAVE_JUMP_LABEL instead of CONFIG_JUMP_LABEL in the Netfilter hook
code as elsewhere in the kernel to resolve toolchain problems, from
Zhouyi Zhou.
5) Use iptunnel_handle_offloads() to set up tunnel encapsulation
depending on the offload capabilities, reported by Alex Gartrell
patch from Julian Anastasov.
6) Fix wrong family when registering the ip_vs_local_reply6() hook,
also from Julian.
7) Select the NF_LOG_* symbols from NETFILTER_XT_TARGET_LOG. Rafał
Miłecki reported that when jumping from 3.16 to 3.17-rc, his log
target is not selected anymore due to changes in the previous
development cycle to accomodate the full logging support for

In certain scenarios a big endian kernel can kexec a little endian kernel.
This patch fixes this case from both ends:
1) Return endianity to original values on shutdown (in case little endian kernel boots after we shutdown).
2) Do not rely on HW reset values when loading driver in little endian kernel
but configure them explicitly (in case previous kernel was big endian and did not reset the HW).

When qeth device is queried for ethtool data, hardware operation
is performed to extract the necessary information from the card.
If the card is not online at the moment (e.g. it is undergoing
recovery), this operation produces undesired effects like
temporarily freezing the system. This patch prevents execution
of the hardware query operation when the card is not online.
In such case, ioctl() operation returns error with errno ENODEV.

The patch fixes race conditions between PCI error recovery callbacks and
potential ifup/ifdown.
First, if ifup (tg3_open) is called between tg3_io_error_detected() and
tg3_io_resume() then tp->timer is armed twice before expiry. Once during
tg3_open() and again during tg3_io_resume(). This results in BUG
at kernel/time/timer.c:945.
Second, if ifdown (tg3_close) is called between tg3_io_error_detected()
and tg3_io_resume() then tg3_napi_disable() is called twice without
a tg3_napi_enable between. Once during tg3_io_error_detected() and again
during tg3_close(). The tg3_io_resume() then hangs on rtnl_lock().
