Re: [PATCH] wext: add back wireless/ dir in sysfs for cfg80211 interfaces

The move away from wireless handlers the drivers assign
to wireless handlers being assigned by cfg80211 broke
the sysfs registration (the wireless/ dir went missing)
because the handlers were assigned only after sysfs
registration and thus the registration never noticed a
device was wireless.

I couldn't make much sense of that: too much assigning!

Fix this by special-casing cfg80211-based devices, all
of which are required to have an ieee80211_ptr, in the
sysfs code, and also using get_wireless_stats() to have
the same values reported as in procfs.

I confirm this works for me too: I won't venture an ignorant opinion
on which is the right solution; but my failed boots do suggest that
keeping away from the notifier infrastructure may make a wiser fix.

Thanks a lot for all your efforts on this, Johannes.
