AVB-DMAC Receive FIFO Warning interrupt is not enabled, so it is not
necessary to disable the interrupt in ravb_close().
On the other hand, this patch disables the interrupt in ravb_dmac_init() to
prevent the possibility that the interrupt is issued by the state that
a boot loader left.

bd1060a1d6 ("sock, cgroup: add sock->sk_cgroup") added global
spinlock cgroup_sk_update_lock but erroneously skipped initializer
leading to uninitialized spinlock warning. Fix it by using

In commit 2a04ae8acb ("hv_netvsc: remove locking in netvsc_send()"), the
locking for MSD (Multi-Send Data) field was removed. This could cause a
race condition between RNDIS control messages and data packets processing,
because these two types of traffic are not synchronized.
This patch fixes this issue by sending control messages out directly
without reading MSD field.

Add support to enable and disable UDP checksums via netlink. This is
similar to how VXLAN and GUE allow this. This includes support for
enabling the UDP zero checksum (for both TX and RX).

100GbE Intel Wired LAN Driver Updates 2015-12-13
This series contains updates to fm10k only.
Jacob updates the driver to use ether_addr_copy() instead of copying
byte-by-byte in a for loop. Fixed up CamelCase variable names and coding
style issues. Cleaned up namespace pollution of fm10k_iov_msg_data_pf().
Cleaned up, by making it consistent, the use of VLAN and VLAN ID instead of
vlan or vid. Lastly, update the driver to initialize XPS so that we can
take advantage of the kernel feature.
Alex Duyck fixed up the driver to free the resources associated with the
MSI-X vector table if the q_vector allocation failed. Then fixed the driver
to check for msix_entries to be NULL and freed the IRQ if the mailbox API
returned an error on trying to connect.
Bruce cleans up whitespace and namespace pollution issues in the driver.
Also updates the driver to use the BIT() macro instead of bit-shifting coding.

Make functions that should be static. While we're at it, fix the function
header comment for fm10k_tlv_attr_nest_stop(), and update the copyright
header for fm10k_pf.h, fm10k_tlv.c and fm10k_tlv.h.

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.

Rather than wrapping fm10k_dcbnl.c and fm10k_debugfs.c support with
#ifdef blocks, just conditionally include the .o files in the Makefile.
Also, since we're modifying it, update the copyright year on the
Makefile.

Instead of using lowercase vlan, vid, or VID, always use VLAN or VLAN ID
in comments when referring to VLANs. The original driver code was
consistent, but recent patches have not been as consistent with this
naming scheme.

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.

Clean up array_rd32 so that it uses igb_rd32 the same as rd32, per the
suggestion of Alexander Duyck, and use io_addr in more places, so that
we don't have the need to call E1000_REMOVED (which simply looks for a
null hw_addr) nearly as much.
