f16704e5e8 i40e/i40evf: use pages correctly in Rx
Refactor the packet split Rx code to properly use half-pages for
receives. The previous code was doing way more mapping and unmapping
than it needed to, and wasn't properly using half-pages.

Increment the page use count each time we give a half-page to an skb,
knowing that the stack will probably process and release the page before
we need it again. Only free and reallocate pages if the count shows that
both half-pages are in use. Add counters to track reallocations and page
reuse.

dd1a5df872 i40e/i40evf: use __GFP_NOWARN
The i40e and i40evf drivers now cleanly handle allocation
failures and can avoid kernel log spew from the memory allocator
when allocations fail, so set __GFP_NOWARN on Rx buffer alloc.

c2e245ab1e i40e/i40evf: try again after failure
This is the "Don't Give Up" patch.  Previously the
driver could fail an allocation, and then possibly stall
a queue forever, by never coming back to continue receiving
or allocating buffers.

With this patch, the driver will keep polling trying to allocate
receive buffers until it succeeds.  This should keep all receive
queues running even in the face of memory pressure.

40d72a5098 i40e/i40evf: don't lose interrupts
While re-enabling interrupts the driver would clear all pending
causes. This meant that if an interrupt was generated while the driver
was cleaning or polling with interrupts disabled, then that interrupt
was lost.  This could cause a queue to become dead, especially for
receive.  Refactored the enable_icr0 function in order to allow
it to be decided by the caller whether the CLEARPBA (clear pending
events) bit will be set while re-enabling the interrupt.

ecc6a239e8 i40e: Refactor force_wb and WB_ON_ITR functionality code
Now that the Force-WriteBack functionality in X710/XL710 devices
has been moved out of the clean routine and into the service task,
we need to make sure WriteBack-On-ITR is separated out since it
is still called from clean.

In the X722 devices, Force-WriteBack implies WriteBack-On-ITR but
without the interrupt, which put the driver into a missed
interrupt scenario and a potential tx-timeout report.

With this patch, we break the two functions out, and call the
appropriate ones at the right place. This will avoid creating missed
interrupt like scenarios for X722 devices.

Also update copyright year in file headers.

8a187f448e i40e: add VEB stat control and remove L2 cloud filter
With the latest firmware, statistics gathering can now be enabled and
disabled in the HW switch, so we need to add a parameter to allow the
driver to set it as desired.  At the same time, the L2 cloud filtering
parameter has been removed as it was never used.

Older drivers working with the newer firmware and newer drivers working
with older firmware will not run into problems with these bits as the
defaults are reasonable and there is no overlap in the bit definitions.
Also, newer drivers will be forced to update because of the change in
function call parameters, a reminder that the functionality exists.

Also update copyright year.

Introduced an inline routine to help determine if the

Moved the firmware version related checks in i40e_sw_init()
and defined flags for different cases

Fix the version check to allow using "Set LLDP MIB" AQ

====================
40GbE Intel Wired LAN Driver Updates 2016-02-16

This series contains updates to i40e/i40evf only.

Shannon adds flags to MAC allocation requests to signify that the MAC VLAN
filters should come from the shared resource pool.  Added a new "set switch
config" admin queue command and the new Cisco VXLAN-GPE cloud tunnel type
for the admin queue commands.  Added more detail to the NVM update debug
message in order to see the full ethtool request data.  Also added a few
more bits of netdev data into the debugfs output for dump VSI.

Pandi fixes the width of two datatypes which were being declared a different
size from what they are assigned.

Anjali fixes an issue where we were not doing write-back on interrupt
throttle for legacy case in x722.

Mitch adds a counter for ARQ overflows since sometimes an ever-growing
number indicates that something bad is happening.  Also added 20G speed for
Tx bandwidth calculations.

Jesse refactors the DCB function based on a community suggestion to change
the multi-level if statement into a switch statement.  Cleans up VF device
IDs in the PF, since it does not need to know them.

or potentially even child qdiscs.

07f169c3e9 i40e: add 20G speed for Tx bandwidth calculations
When calculating TX bandwidth for VFs, we need to know the link speed to
make sure we don't allocate more bandwidth than is available. Add 20G
link speed to the switch statement so we can support devices that link
at that speed.

1d0a4ada84 i40e: add counter for arq overflows
Sometimes, ARQ overflows are a big deal and tell us that the
firmware/hardware/driver/something is having problems. But normally
they're no big deal. To assist in assessing this, add a counter to
our Ethtool stats. A handful of ARQ overflows during VF init is no
problem. A large, ever-growing number indicates that Something Bad is
happening.

a3d772a392 i40e: fix write-back-on-itr to work with legacy itr
We were not doing write-back on interrupt throttle for Legacy case in X722.
This patch fixes that, so we do WB_ON_ITR for Legacy as well. Plus the issue
that we should still be setting NO_ITR if we are touching the DYN_CTLN register
since we do not want to change ITR setting here.
