Given the intent behind gpiod_get_optional() and friends it does not make
sense to return -ENOSYS when GPIOLIB is disabled: the driver is expected to
work just fine without gpio so let's behave as if gpio was not found.
Otherwise we have to special-case -ENOSYS in drivers.
Note that there was objection that someone might forget to enable GPIOLIB
when dealing with a platform that has device that actually specifies
optional gpio and we'll break it. I find this unconvincing as that would
have to be the *only GPIO* in the system, which is extremely unlikely.

Our original filter limit of 8 was based on behavior that we saw from
Linux VMs. Now we're running Other Operating Systems under KVM and we
see that they commonly use more MAC filters. Since it seems weird to
require people to enable trusted VFs just to boot their OS, bump the
number of filters allowed by default.

This patch adds support for DMA_ATTR_SKIP_CPU_SYNC and
DMA_ATTR_WEAK_ORDERING. By enabling both of these for the Rx path we
are able to see performance improvements on architectures that implement
either one due to the fact that page mapping and unmapping only has to
sync what is actually being used instead of the entire buffer. In addition
by enabling the weak ordering attribute enables a performance improvement
for architectures that can associate a memory ordering with a DMA buffer
such as Sparc.

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().

(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.

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.
