Just like with any other frame, mac80211 will do sanity checks
on no-data RX (representing e.g. sounding PPDUs), and if e.g.
the NSS is wrong, it will warn. This isn't a good idea if we
already know the frame wasn't received well, e.g. has bad PLCP.
Unless the firmware reports "no error", set the bad PLCP flag
to skip checks in mac80211.
Also, since we're now extracting two different values from the

lq_sta being NULL as mac80211 will (no longer) call us like
that, and since I removed the rate_control_send_low() call in
this function there's no longer any point in setting priv_sta

So the only thing that remains to check is if we have actually
initialized our lq_sta->drv pointer, and exit if we didn't in
which case we'll use the data mac80211 already set up for the
low rate usage.

The default netdev interface exposed by WILC1000 is registered at probe,
but the chip mac address is not known until ndo_open, which will load and
start chip firmware and then retrieve stored MAC address from it. As a
consequence, the interface has uninitialized value (00:00:00:00:00) until a
user brings up the interface.
Fix MAC address at probe by setting the following steps:
- at probe, read MAC address directly from fuse
- whenever a new netdevice is created, apply saved mac address (which can
be a user-provided address, or the eFuse Mac address if no address has
been passed by user)
- whenever an interface is brought up for the first time (and so the
firmware is loaded and started), enforce netdevice mac address to the
chip (in case user has changed it)

In order to be able to read raw registers (eg the nv mac address) in

run the basic sdio functions initialization, but then we also need to
properly deinitialize those right after, to preserve the current driver
behavior (keeping the chip idle/unconfigured until the corresponding
interface is brought up). Calling wilc_sdio_deinit in its current form is
not enough because it merely resets an internal flag.
Implement a deinit sequence which symmetrically reset all steps performed

wilc_netdev_ifc_init. However, bus is still not fully initialized when we
register corresponding net device (for example we still miss some private
driver data pointers), which for example makes it impossible to
retrieve MAC address from chip (which is supposed to be set on net device
before its registration) before registering net device. More generally, net
device registration should not be done until driver has fully initialized
everything and is ready to handle any operation on the net device.

====================
netdevsim: add NAPI support
Add NAPI support to netdevsim and register its Rx queues with NAPI
instances. Then add a selftest using the new netdev Python selftest
infra to exercise the existing Netdev Netlink API, specifically the
queue-get API.
This expands test coverage and further fleshes out netdevsim as a test
device. It's still my goal to make it useful for testing things like
flow steering and ZC Rx.
