[PATCH wireless-next v3 4/7] wifi: mac80211: add cigtk parameter to ieee80211_gtk_rekey_add

[Benjamin Berg]

From: Benjamin Berg <benjamin.berg at intel.com>

The CIGTK keys use a key index of 0 or 1, which is not unique. As such,
a new parameter is needed to differentiate the key type. Add the
parameter to prepare for handling the CIGTK in the future.
