This will allow us to fix crashes in ath10k (and possibly other drivers). To summarize Johannes' explanation: Consider add interface wlan0 add interface wlan1 iterate active interfaces -> wlan0 wlan1 add interface wlan2 iterate active interfaces -> wlan0 wlan1 wlan2 If you apply this scenario to a restart, which ought to be functionally equivalent to the normal startup, just compressed in time, you're basically saying that today you get add interface wlan0 add interface wlan1 iterate active interfaces -> wlan0 wlan1 wlan2 << problem here add interface wlan2 iterate active interfaces -> wlan0 wlan1 wlan2 which yeah, totally seems wrong. But fixing that to be add interface wlan0 add interface wlan1 iterate active interfaces -> add interface wlan2 iterate active interfaces -> (or maybe -> wlan0 wlan1 wlan2 if the reconfig already completed) This is also at least somewhat wrong, but better to not iterate over something that exists in the driver than iterate over something that does not. Originally the first issue was causing crashes in testing with lots of station vdevs on an ath10k radio, combined with firmware crashing. I ran with a similar patch for years with no obvious bad results, including significant testing with ath9k and ath10k.
