Jeff Kirsher says:

====================
Intel Wired LAN Driver Updates

This series contains updates to i40e only.

Anjali provides two cleanups to remove unnecessary code and a fix
to resolve debugfs dumping only half the NVM.  Then provides a fix
to ethtool NVM reads where shadow RAM was used instead of actual
NVM reads.

Jesse provides a couple of fixes, one removes custom i40e functions
which duplicate existing kernel functionality.  Second fixes constant
cast issues by replacing __constant_htons with htons.

Mitch provides a couple of fixes for the VF interfaces in i40e.  First
provides a fix to guard against VF message races with can cause a panic.
Second fix reinitializes the buffer size each time we clean the ARQ,
because subsequent messages can be truncated. Lastly adds functionality
to enable/disable ICR 0 dynamically.

Vasu adds a simple guard against multiple includes of the i40e_txrx.h
file.

Shannon provides a couple of fixes, first fix swaps a couple of lines
around in the error handling if the allocation for the VSI array fails.
Second fixes an issue where we try to free the q_vector that has not
been setup which can panic the kernel.

David provides a patch to save off the point to memory and the length
of 2 structs used in the admin queue in order to store all info about
allocated kernel memory.

Neerav fixes ring allocation where allocation and clearing of rings
for a VSI should be using the alloc_queue_pairs and not num_queue_pairs.
Then removes the unused define for multi-queue enabled.
