I did not even look there, shame on me :(

Anyway, now I have put

compat.linuxkpi.skb.mem_limit=1

into /boot/loader.conf. This device has 16 GB RAM, so it surely
qualifies for this workaround... Is there something else I should have
find there?

After reboot, wireless works (tested with ping to gateway on wireless
segment), but there are multiple

wlan0: link state changed to DOWN
rtw880: lkpi_iv_newstate: error 95 during state transition 2 (AUTH) -> 2 (AUTH)
wlan0: link state changed to UP

lines seen on console. Maybe that's just cosmetics, I don't know yet.

Also, on if_rtw88.ko autoload, seeing this

rtw880: <rtw_8821ce> port 0x3000-0x30ff mem 0x80400000-0x8040ffff at device 0.0 on pci1
rtw8821c_fw.bin: could not load binary firmware /boot/firmware/rtw8821c_fw.bin either
rtw88/rtw8821c_fw.bin: could not load binary firmware /boot/firmware/rtw88/rtw8821c_fw.bin either
rtw88_rtw8821c_fw.bin: could not load binary firmware /boot/firmware/rtw88_rtw8821c_fw.bin either
rtw880: successfully loaded firmware image 'rtw88/rtw8821c_fw.bin'
rtw880: Firmware version 24.11.0, H2C version 12

I think lines 2-4 are just some failed attempts and as firmware module
rtw88_rtw8821c_fw_bin.ko is autoloaded, they are somehow misleading,
and maybe should be subject to rewrite.

I am going to test it a bit, if you have anything I can try, let me
know.
