[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) Signed-off-by: James Ketrenos <jketreno@linux.intel.com> Signed-off-by: Jeff Garzik <jgarzik@pobox.com>
