mac80211: use cipher suite selectors
Currently, mac80211 translates the cfg80211 cipher suite selectors into ALG_* values. That isn't all too useful, and some drivers benefit from the distinction between WEP40 and WEP104 as well. Therefore, convert it all to use the cipher suite selectors. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Acked-by: Gertjan van Wingerde <gwingerde@gmail.com> Signed-off-by: John W.
