In order to avoid keeping work like tx scheduling pinned to the CPU it was

Unlike a workqueue, this one only allows one fixed worker function to be
executed by the worker thread. Because of that, there is less locking

mt76: mt7915: clean up station stats polling and rate control update

Queueing a per-sta work item from the tx free path can become very expensive
under load. This work is only supposed to pull rate control stats every
second and deal with rate control changes.

Additionally, the rate control update code was wrong, because it was
confusing bit masks and bit numbers in test_bit.

Fix this by introducing a dedicated device work item for rate control
updates, and by polling station stats from the phy mac work.
Stations requiring polling or rate control updates are added to lists

net: wilc1000: clean up resource in error path of init mon interface

The wilc_wfi_init_mon_int() forgets to clean up resource when
register_netdevice() failed. Add the missed call to fix it.
And the return value of netdev_priv can't be NULL, so remove
the unnecessary error handling.
