FWIW, many drivers now don't do it on IFF_UP/start any more but do
request_firmware_nowait() in probe and only finish probing and
registering with mac80211 when they have the firmware file. This is
necessary if you have any device/driver capabilities that depend on the
firmware that need to be known before registering with mac80211.
