Currently, mac80211 allows key installation only after association completes. However, Enhanced Privacy Protection Key Exchange (EPPKE) requires key installation before association to enable encryption and decryption of (Re)Association Request and Response frames. Add support to install keys prior to association when the peer is an Enhanced Privacy Protection (EPP) peer that requires encryption and decryption of (Re)Association Request and Response frames. Introduce a new boolean parameter "epp_peer" in the "ieee80211_sta" profile to indicate that the peer supports the Enhanced Privacy Protection Key Exchange (EPPKE) protocol. For non-AP STA mode, it is set when the authentication algorithm is WLAN_AUTH_EPPKE during station profile initialization. For AP mode, it is set during NL80211_CMD_NEW_STA and NL80211_CMD_ADD_LINK_STA. When "epp_peer" parameter is set, mac80211 now accepts keys before association and enables encryption of the (Re)Association Request/Response frames.
