nl80211: New command for adding extra IE(s) into management frames
A new nl80211 command, NL80211_CMD_SET_MGMT_EXTRA_IE, can be used to add arbitrary IE data into the end of management frames. The interface allows extra IEs to be configured for each management frame subtype, but only some of them (ProbeReq, ProbeResp, Auth, (Re)AssocReq, Deauth, Disassoc) are currently accepted in mac80211 implementation. This makes it easier to implement IEEE 802.11 extensions like WPS and FT that add IE(s) into some management frames. In addition, this can be useful for testing and experimentation purposes.
