nl80211 : Add support for configuring MFP
NL80211_CMD_ASSOCIATE request must be able to indicate whether management frame protection (IEEE 802.11w) is being used. mac80211 was able to use MFP in client mode only with WEXT, but the new NL80211_ATTR_USE_MFP attribute will allow this to be done with nl80211, too. Since we are currently using nl80211 for MFP only with drivers that use user space SME, only MFP disabled and required values are used. However, the NL80211_ATTR_USE_MFP attribute is an enum that can be extended with MFP optional in the future, if that is needed with some drivers (e.g., if the RSN IE is generated by the driver).
