mt76_scan_complete() restores the operating channel only if the phy has one. __mt76_set_channel() is the only function that clears phy->offchannel. A phy can run a scan while it has no operating channel. A 6 GHz radio with no configured interface is one example. After such a scan, the flag stays set. mt76_txq_schedule_list() skips each TXQ whose wcid points to a phy in this state. All traffic for the stations on that band stops. The frames stay in the mac80211 queues. They do not reach the hardware, and no counter shows them. Only an unrelated channel set clears the flag.
