I agree with Jouni, this is probably not a good idea, especially since
this flag would be shared between hardware for those drivers that have
the channel structs allocated statically. We should probably just stick
a struct ieee80211_channel *switch_from; pointer somewhere into the
sdata struct or so.

I think I'd like to have them dropped to monitor for !station here,
instead of silently in the processing function.

That should probably be removed or be more specific & protected by some
debug #ifdef.

Can you rebase this on top of Kalle's patch that adds the "stop reasons"
for each queue? As it is now, the driver could wake up the queues again
if one was full.
