Subject: [PATCH] rtw88: add ieee80211_ops::change_interface
Git-commit: 40b788d15832f5947b6d4e4ff3afea9af267bac6
Patch-mainline: v5.9-rc1
References: jsc#SLE-13430, bsc#1176741
Sometimes mac80211 will just ask driver to change the interface
instead of to remove and then add a new one. And for driver, to
change the interface is just simply to remove and add a new one
but change the type of it.
