mac80211: properly track HT operation_mode
When we disassociate, we set the channel to non-HT which obviously invalidates any ht_operation_mode setting. But when we then associate with the next AP again, we might still have the ht_operation_mode from the previous AP cached and fail to configure the hardware with the new (but unchanged) operation mode. This patch fixes it by separately tracking whether our cache is valid. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W. Linville <linville@tuxdriver.com>
