[PATCH] ieee80211: in-tree driver updates to sync with latest ieee80211 series

Changed crypto method from requiring a struct ieee80211_device reference
to the init handler.  Instead we now have a get/set flags method for
each crypto component.

Setting of TKIP countermeasures can now be done via
set_flags(IEEE80211_CRYPTO_TKIP_COUNTERMEASURES)
