Hiya, It looks like I last used compat-wireless successfully was on
25th (I am not saying it breaks after - I just haven't tried until
yesterday, possibly), and most of the recent changes are per-driver,
but there is a big code drop from Johannes dated 27th on 'wext:
refactor' . Changes from that or dependent changes?
