mac80211: driver can remain on channel if not using chan_ctx
Some of the drivers are not using channel context, but let the stack to control/switch channels instead. For such cases, driver can still remain on channel because the mac80211 stack actually supports it. The stack will check if the driver is using chan_ctx and has ops->remain_on_channel been hooked. Otherwise it will start its ROC work to remain on channel. So, even if the driver is not using chan_ctx, the driver is still capable of doing remain on channel.
