MFC_NOTIFY was introduced in kernel 2.1.68 but afaik it hasn't been used
and I couldn't find any users currently so just remove it. Only
MFC_STATIC is left, so move it into an enum, add a description and use

Intel Wired LAN Driver Updates 2015-11-25
This series contains updates to fm10k, i40e and i40evf.
Alex Duyck fixes up fm10k to use napi_schedule_irqoff() instead of
napi_schedule() since the function it is called from runs from hard interrupt
context or with interrupts already disabled in netpoll.
Shannon cleans up i40e and i40evf unused cd_tunneling parameter and any code
comments that refer to it. Then clean up a few instances of BUG_ON, based
on a Linux diatribe, especially when WARN_ON can be used.
Helin fixed a issue where using ethtool RXNFC command could let receive
flow hash could be set on disabled queues, so resolve by returning the
number of enabled queues before setting RXNFC.
Anjali fixes a MSS issue where the hardware/NVM sets a limit of no less than
256 bytes for MSS, yet the stack can send as low as 76 byte MSS. Fixed the
issue by lowering the hardware limit to 64 bytes to avoid MDDs from firing
and causing a reset when the MSS is lower than 256. Added a statistic to
track how many times we forced to do a write back on transmit if the
number of descriptors pending are less than a cache line.
Catherine fixes link status changes, where polling would only change link
status changes in one direction depending on what the last old data saved
off was. This was due to the watchdog only calling link_event and not
handle_link_event.
Mitch cleans up and enhances error messages related to VF MAC/VLAN filters.

When a lot (many hundreds) of MAC or VLAN filters are added at one time,
we can overflow the Admin Queue buffer size with all the requests.
Unfortunately, the driver would then calculate the message size
incorrectly, causing it to be rejected by the PF. Furthermore, there was
no mechanism to trigger another request to allow for configuring the
rest of the filters that didn't fit into the first request.
To fix this, recalculate the correct buffer size when we detect the
overflow condition instead of just assuming the max buffer size. Also,
don't clear the request bit in adapter->aq_required when we have an
overflow, so that the rest of the filters can be processed later.

OK
IP-Config: Got DHCP answer from 192.168.97.254,
my address is 192.168.97.44
Convert these back to using pr_cont(), so it prints again:
., OK
IP-Config: Got DHCP answer from 192.168.97.254, my address is 192.168.97.44
Absorb the printing of "my address ..." into the previous call to

build errors in configurations that disable CONFIG_GPIOLIB:
net/dsa/dsa.c:783:16: error: implicit declaration of function 'gpio_to_desc' [-Werror=implicit-function-declaration]
The reason is that linux/gpio/consumer.h is not automatically
included without gpiolib support. This adds an explicit #include
statement to make it compile in all configurations. The reset
functionality will not work without gpiolib, which is what you
get when disabling the feature.
As far as I can tell, gpiolib is supported on all architectures

Intel Wired LAN Driver Updates 2015-11-23
This series contains updates to ixgbe, ixgbevf, fm10k, i40e and i40evf.
Jacob fixes an issue where VF could attempt to read queues it does not own,
so prevent this we check queue 0 before we continue.
Matthew fixes the MTU for jumbo frames for fm10k.
Julia Lawall cleans up a unneeded NULL test in ixgbe.
Mark cleans up a redundant header inclusion. Adds KR mode support for
CS4227 chip. Cleaned up diagnostic code, which is no longer needed, for
the CS4227 chip.
Jean Sacren fixes kernel documentation for ixgbe.
Alex Duyck fixes an fm10k and ixgbe issue in which the polling routine would
increase the budget for receive to at least 1 per queue if multiple queues were
present. This would result in receive packets being processed when the budget
was 0 which is meant to indicate that no receive can be handled. Also fixes
an ixgbevf performance issue where netperf test will starve for memory in the
time form one transmit interrupt to the next, so limit lowest interrupt rate
for adaptive interrupt moderation to 12K. Fixed up ixgbe and ixgbevf to
use napi_schedule_irqoff() where the drivers were run from hard interrupt
context or with interrupts already disabled in netpoll.
Jesse fixes a compiler warning about an unused variable for i40evf.
John Greene fixes an issue with ixgbevf, where if the VF driver is loaded
while the corresponding PH interface is down, the driver assigns a random
MAC address, can be overwritten with the value of hw->mac.perm_addr which
is 0 at that point. So avoid this case by initializing hw->mac.perm_addr
to the randomly generated address and do not set it unless we receive an
ACK from ixgbe.
Rasmus Villemoes cleans up some confusing code in i40e debugfs code.
