Some opcodes added & reordered to be in numerical order with the
rest of the opcodes. Several structs that were added are unnecessary,
so they are removed here. This patch adds admin queue structs to
support Wake on LAN feature for X722.

From: Mitch Williams <mitch.a.williams@intel.com>
In preparation for upcoming RDMA-capable hardware, add a client
interface to the VF driver. This is a slightly-simplified version
of the PF client interface, with the names changed to protect the
innocent.
Due to the nature of the VF<->PF interactions, the client interface
sometimes needs to call back into itself to pass messages. Because
of this, we can't use the coarse-grained locking like the PF's
client interface uses. Instead, we handle all client interactions
in a separate thread so the watchdog can still run and process
virtual channel messages.

From: Mitch Williams <mitch.a.williams@intel.com>
(KISS is Keep It Simple, Stupid. Or is it?)
The client interface vastly overengineered for what it needs to do.
It was originally designed to support multiple clients on multiple
netdevs, possibly even with multiple drivers. None of this happened,
and now we know that there will only ever be one client for i40e
(i40iw) and one for i40evf (i40iwvf). So, time for some KISS. Since
i40e and i40evf are a Dynasty, we'll simplify this one to match the
VF interface.
First, be a Destroyer and remove all of the lists and locks required
to support multiple clients. Keep one static around to keep track of
one client, and track the client instances for each netdev in the
driver's pf (or adapter) struct. Now it's Almost Human.
Since we already know the client type is iWarp, get rid of any checks
for this. Same for VSI type - it's always going to be the same type,
so it's just a Parasite.
While we're at it, fix up some comments. This makes the function
headers actually match the functions.
These changes reduce code complexity, simplify maintenance,
squash some lurking timing bugs, and allow us to Rock and Roll All
Nite.

This is a solution to avoid adding too many queues to num_lan_msix.
A recent refactor of queue pairs accidentally added all remaining
vectors to the num_lan_msix which can have adverse performance issues,
due to enabling more queues than the number of CPU cores.
This patch removes the old calculation, and replaces it with a simple
algorithm.
1) add queue pairs up to num_online_cpus(), but capped at half of total
vectors
2) then add alternative features such as flow directory and similar
3) finally, add the remaining vectors back to queue pairs, but capped
such that the total number of queue pairs does not exceed
num_online_cpus().

Hi
I requested Jeff to remove this series from Intel-wired-lan.
Please ignore this one. I will be uploading correct series soon.

From: Shannon Nelson <shannon.nelson@intel.com>
Some opcodes added & reordered to be in numerical order with the
rest of the opcodes. Several structs that were added are unnecessary,
so they are removed here. This patch adds admin queue structs to
support Wake on LAN feature for X722.

This still doesn't look right. I think the last line here needs to be dropped. Otherwise why have the else block at all, and why set num_msix_vectors separately in the first section? Ya, basically the code upstream doesn't have all of the CLIENT_ENABLED bits here. You need to drop the last line here I just marked, or you need to drop all the client enabled bits. Since the original code doesn't have the CLIENT_ENABLED portion, I suggest dropping that part for now and re-adding client support to this in a future patch.
