Subject: [PATCH 09/20] wifi: rtl8xxxu: support multiple interfaces in set_aifs()
Date: Mon, 18 Dec 2023 15:36:34 +0100

In concurrent mode supported by this driver, both interfaces will use
the same channel and same wireless mode.
It is therefore possible to get the wireless mode by checking the first
connected interface.
