mac80211: remove wep dependency
The current mac80211 code assumes that WEP is always available. If WEP fails to initialize, ieee80211_register_hw will always fail. In some cases (e.g. FIPS certification), the cryptography used by WEP is unavailable. However, in such cases there is no good reason why CCMP encryption (or even no link level encryption) cannot be used. So, this patch removes mac80211's assumption that WEP (and TKIP) will always be available for use. Signed-off-by: John W. Linville <linville@tuxdriver.com>
