Dear Maintainer,

Using kernel 6.5 from backports I am unable to acquire an IPv6 address
on my mediatek 7921 wifi card. It works in 6.1 (but that one is much
less power-efficient on my ryzen system).

If I update the WIFI_MT7922_patch_mcu_1_1_hdr.bin and
WIFI_RAM_CODE_MT7922_1.bin files with the latest version from kernel
everything works, also in 6.1.

I've downloaded the files from
https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/commit/mediatek/WIFI_MT7922_patch_mcu_1_1_hdr.bin?id=6b91b2ef6f4173099c1434e5d7c552e51814e26e
and https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/commit/mediatek/WIFI_RAM_CODE_MT7922_1.bin?id=6b91b2ef6f4173099c1434e5d7c552e51814e26e
