Add support for Extended Key ID in hostapd based on IEEE 802.11 - 2016 for infrastructure (AP) connections. This also fixes an off by one error for key tracking and deletion: Even within IEEE 802.11w the highest keyid is 5 and not 6. Signed-off-by: Alexander Wetzel <alexander@wetzel-home.de> --- This complements the hostapd Extended Key ID patch and adds support for it also to wpa_supplicant. For now we only have the "client" Extended Key ID support covered in wpa_supplicant. IBSS/TDLS/mesh extensions are also missing for now but besides that it's feature complete.
