wifi: mac80211: simplify non-chanctx drivers

There are still surprisingly many non-chanctx drivers, but in
mac80211 that code is a bit awkward. Simplify this by having
those drivers assign 'emulated' ops, so that the mac80211 code
can be more unified between non-chanctx/chanctx drivers. This
cuts the number of places caring about it by about 15, which
are scattered across - now they're fewer and no longer in the
channel context handling.

wifi: rt2x00: use explicitly signed or unsigned types

On some platforms, `char` is unsigned, but this driver, for the most part,
assumed it was signed. In other places, it uses `char` to mean an
unsigned number, but only in cases when the values are small. And in
still other places, `char` is used as a boolean. Put an end to this
confusion by declaring explicit types, depending on the context.

wifi: mac80211: add wake_tx_queue callback to drivers

mac80211 is fully switching over to the internal TX queue (iTXQ)
implementation. Update all drivers not yet providing the now mandatory
wake_tx_queue() callback.

As an side effect the netdev interfaces of all updated drivers will
switch to the noqueue qdisc.

00:0C:43:30:60:00). Using multiple of these devices in the same network
can cause nasty issues.

Allow to override the MAC in the EEPROM with (a known good) one set in

rt2x00: fix monitor mode regression

Since commit df1404650ccb ("mac80211: remove support for IFF_PROMISC")
monitor mode for rt2x00 has been made effectively useless because the
hardware filter is configured to drop packets whose intended recipient is
not the device, regardless of the presence of monitor mode interfaces.

This patch fixes this regression by adding explicit monitor mode support,
and by configuring the hardware filter accordingly.
