cfg80211/nl80211: support GTK rekey offload
In certain circumstances, like WoWLAN scenarios, devices may implement (partial) GTK rekeying on the device to avoid waking up the host for it. In order to successfully go through GTK rekeying, the KEK, KCK and the replay counter are required. Add API to let the supplicant hand the parameters to the driver which may store it for future GTK rekey operations. Note that, of course, if GTK rekeying is done by the device, the EAP frame must not be passed up to userspace, instead a rekey event needs to be sent to let userspace update its replay counter.
