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. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
