I have a laptop using an AX210 network card (no ethernet), which is supported by -current, but not by 7.1. I installed 7.1 without configuring network, rebooted, and dumped the iwx firmware 20220708 onto a USB key.
I tried to fw_update -p . but it did not detected iwx as added iwx. I tried fw_update -p . iwx, it added iwx, updated none, kept none. The interface did not showed up with ifconfig. Then I sh /etc/netstart, it does not output anything, and the interface does not appear. Running fw_update -d iwx yields "No firmware found for iwx", which makes me think that the previous fw_update command did not worked. - Quentin
