This patch addresses two issues.
First is the fact that the fm10k_mbx_free_irq was assuming msix_entries was
valid and that will not always be the case. As such we need to add a check
for if it is NULL.
Second is the fact that we weren't freeing the IRQ if the mailbox API
returned an error on trying to connect.

Jan Stancek reported that I wrecked things for him by fixing things for
Vladimir :/
His report was due to an UNINTERRUPTIBLE wait getting -EINTR, which
should not be possible, however my previous patch made this possible by
unconditionally checking signal_pending().
We cannot use current->state as was done previously, because the
instruction after the store to that variable it can be changed. We must
instead pass the initial state along and use that.

1GbE Intel Wired LAN Driver Updates 2015-12-12
This series contains updates to e1000, e1000e and igb.
Joern Engel fixes up the e1000 driver to reduce scheduler latencies by
making the eeprom read/write functions scheduler friendly by using a mutex
lock instead of a spin lock.
Todd adds code for igb to initialize the 88E1543 PHY properly. Then fixed
igb to use the correct i210 register for EEMNGCTL, since the i210 has two
EEPROM access registers (EEARBC and EEMNGCTL).
Dmitry Vyukov provides a fix for e1000 to resolve a data race found with
KernelThreadSanitizer (KTSAN), where no memory barriers were being used
when buffers get recycled, so the recycled buffers can be corrupted. So
use smp_store_release() to update tx_ring->next_to_clean and
smp_load_acquire() to read tx_ring->next_to_clean to properly hand off
buffers from e1000_clean_tx_irq() to e1000_xmit_frame().
Jarod Wilson fixes igb so that we do not try to unmap a NULL hw_addr. Then
cleaned up array_rd32() so that it uses igb_rd32() the same as rd32() and
use io_addr() in more places so that we do not have to call E1000_REMOVED().
Janusz Wolak cleans up the e1000 driver by correcting warnings produced
by checkpatch.pl for the driver.
Jean Sacren provides several patches with general cleanups for e1000 and
e1000e, which include code comment fix-ups and cleanup of local variables
not needed.
Dmitry Fleytman fixes a possible division by zero in the receive interrupt
handler for e1000e when working without adaptive interrupt moderation,
which is typically disabled on jumbo MTUs.
Raanan increases the timeout of the polling bit due to timing changes to
the ME firmware on a platform, so increase the timeout to 300ms. Added
initial support for i219-LM, which is a LOM that will be available on
systems with the Lewisburg Platform Controller HUB (PCH) chipset.
Jan Beulich fixes a NULL dereference in igb, due to the adapter->vf _data
being NULL while adapter->vfs_allocated_count is non-zero.

When we use 'nft -f' to submit rules, it will build multiple rules into
one netlink skb to send to kernel, kernel will process them one by one.
meanwhile, it add the trans into commit_list to record every commit.
if one of them's return value is -EAGAIN, status |= NFNL_BATCH_REPLAY
will be marked. after all the process is done. it will roll back all the
commits.
now kernel use list_add_tail to add trans to commit, and use
list_for_each_entry_safe to roll back. which means the order of adding
and rollback is the same. that will cause some cases cannot work well,
even trigger call trace, like:
1. add a set into table foo [return -EAGAIN]:
commit_list = 'add set trans'
2. del foo:
commit_list = 'add set trans' -> 'del set trans' -> 'del tab trans'
then nf_tables_abort will be called to roll back:
firstly process 'add set trans':
case NFT_MSG_NEWSET:
trans->ctx.table->use--;
list_del_rcu(&nft_trans_set(trans)->list);
it will del the set from the table foo, but it has removed when del
table foo [step 2], then the kernel will panic.
the right order of rollback should be:
'del tab trans' -> 'del set trans' -> 'add set trans'.
which is opposite with commit_list order.
so fix it by rolling back commits with reverse order in nf_tables_abort.

40GbE Intel Wired LAN Driver Updates 2015-12-12
This series contains updates to i40e and i40evf only.
Jesse fixes some trivial static analyzer warnings where BIT() can be used
instead of BIT_ULL().
Mitch fixes the virtual channel interface which was using incorrect semantics
to remove MAC addresses and would leave incorrect filters active when using
VLANs. Also fixes an issue that when VF's are created, the MAC address
defaults to all zeros, indicating to the VF driver that it should use a
random MAC address. However, the PF driver was incorrectly adding this
zero MAC to the filter table, so check for a good address before adding
the default filter. Adds a check to make sure that the Tx and Rx rings
actually exist before dereferencing them to free resources. Re-classifies
several messages which are really for debugging purposes, especially since
the driver can fully recover from any of these. Fixed up the VF version
strings to match the PF driver.
Anjali adds a virtchnl offload to support the expanded version of TCP/UDP
PCTYPES for RSS.
Shannon fixes i40e to clean the whole MAC filter list when resetting after
an intermediate add or delete push to the firmware.
v2: added blank line after variable declaration in patch 9 based on
feedback from Sergei Shtylyov <sergei.shtylyov@cogentembedded.com>

The combined effect of commits 6423fc3416 ("igb: do not re-init SR-IOV
during probe") and ceee3450b3 ("igb: make sure SR-IOV init uses the
right number of queues") causes VFs no longer getting set up, leading
to NULL pointer dereferences due to the adapter's ->vf_data being NULL
while ->vfs_allocated_count is non-zero. The first commit not only
neglected the side effect of igb_sriov_reinit() that the second commit
tried to account for, but also that of setting IGB_FLAG_HAS_MSIX,
without which igb_enable_sriov() is effectively a no-op. Calling
igb_{,re}set_interrupt_capability() as done here seems to address this,
but I'm not sure whether this is better than sinply reverting the other
two commits.

The checking logic needed some clean-up work, so we rewrite it by
checking for break first. With that change in place, we can even move
the second check for goto statement outside of the loop.
As this is merely a cleanup, no functional change is involved. The
questionable 'tmp != 0xFF' is intentionally left alone.

Upon looking at the igb driver, I see that igb_rd32() attempted to read from
hw_addr and failed, so it set hw->hw_addr to NULL and spit out the message
in the log output above, "PCIe link lost, device now detached".
Well, now that hw_addr is NULL, the attempt to call pci_iounmap is obviously
not going to go well. As suggested by Mark Rustad, do something similar to
what ixgbe does, and save a copy of hw_addr as adapter->io_addr, so we can
still call pci_iounmap on it on teardown. Additionally, for consistency,
make the pci_iomap call assignment directly to io_addr, so map and unmap
match.

e1000_clean_tx_irq cleans buffers and sets tx_ring->next_to_clean,
then e1000_xmit_frame reuses the cleaned buffers. But there are no
memory barriers when buffers gets recycled, so the recycled buffers
can be corrupted.
Use smp_store_release to update tx_ring->next_to_clean and
smp_load_acquire to read tx_ring->next_to_clean to properly
hand off buffers from e1000_clean_tx_irq to e1000_xmit_frame.
The data race was found with KernelThreadSanitizer (KTSAN).

Generate version strings like the PF driver does. This gives us more

Clean the whole mac filter list when resetting after an intermediate
add or delete push to the firmware. The code had evolved from using
a list from the stack to a heap allocation, but the memset() didn't
follow the change correctly. This now cleans the whole list rather
that just part of the first element.

X722 supports Expanded version of TCP, UDP PCTYPES for RSS.
Add a Virtchnl offload to support this.
Without this patch with X722 devices, driver will set wrong PCTYPES
for VF and UDP flows will not fan out.

These messages seem big and scary, but they're really not. The driver
can fully recover from any of these. The overflow error in particular
can happen when enabling a bunch of VFs and the VF driver is not
blacklisted.
Since these messages are really for debugging purposes, reclassify
them as such.

new NVM arq message
This is a part of implementation which contains data structures and
opcode for new AQ command. There's a new ARQ message that gets sent
near the end of the NVM update process that the driver should recognize
and ignore, rather than printing an Unknown Event error.
