When TKIP support was added, we stored the keys separately to avoid issues when both TKIP and WEP keys are sent to the driver. We need to consolidate the storage to convert to cfg80211, so do this first and try iron out the issues. Signed-off-by: David Kilroy <kilroyd@googlemail.com> Signed-off-by: John W.
