receive direction, while software handles WEP in the transmit direction. When net80211 calls rtw's rtw_key_set with a WEP key, I point the key's wk_cipher at our "fake" cipher, rtw_cipher_wep, which is alike to ieee80211_cipher_wep except it provides a different crypto-decapsulation routine, rtw_wep_decap. rtw_wep_decap copies the key passed to it by net80211, clears the key's SWCRYPT flag, and then calls wep_decap. Now wep_decap will decapsulate, but it will *not* re-decrypt. XXX I need to check whether the hardware supports 40-bit WEP, XXX 104-bit WEP, or both, and act accordingly.
