e5497d766a 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.

830af02f24 mac80211: allow driver to iterate keys
When in suspend/wowlan, devices might implement crypto
offload differently (more features), and might require
reprogramming keys for the WoWLAN (as it is the case
for Intel devices that use another uCode image). Thus
allow the driver to iterate all keys in this context.

3bff186518 mac80211: Skip tailroom reservation for full HW-crypto devices with race fix
Based on inputs from Johannes Berg <johannes@sipsolutions.net>
from http://article.gmane.org/gmane.linux.kernel.wireless.general/68193
and http://article.gmane.org/gmane.linux.kernel.wireless.general/71702

In xmit path, devices that do full hardware crypto (including
MMIC and ICV) need no tailroom. For such devices, tailroom
reservation can be skipped if all the keys are programmed into
the hardware (i.e software crypto is not used for any of the
keys) and none of the keys wants software to generate Michael
MIC and IV.

v2: Added check for IV along with MMIC.
