mac80211 will be called via cfg80211, and will run __ieee80211_suspend()
which calls a whole bunch of driver things. This is _before_ the
driver's suspend() callback runs.
Then, after the driver's resume() callback runs, we go into
ieee80211_reconfig() in mac80211.
You can find the interaction with the PM subsystem in
net/wireless/sysfs.c.
