If anyone has any objections, please let me know. ------------------ From: Johannes Berg commit 115b943a6ea12656088fa1ff6634c0d30815e55b upstream. Jouni reported that when doing off-channel transmissions mixed with on-channel transmissions, the on-channel ones ended up on the off-channel in some cases. The reason for that is that during the refactoring of the off- channel code, I lost the part that stopped all activity and as a consequence the on-channel frames (including data frames) were no longer queued but would be transmitted on the temporary channel. Fix this by simply restoring the lost activity stop call.
