Bug#1081114: linux: Please enable CONFIG_MT7925E=m, CONFIG_MT7925U=m

[Robert Edmonds <edmonds@debian.org>]

Package: linux
Severity: wishlist

Dear maintainers,

Please enable support for MediaTek Wi-Fi 7 adapters based on the
mt7925 driver. These adapters can be purchased now (e.g. the AzureWave
AW-EB600NF M.2 module) but the driver for these adapters is not enabled
in the Debian kernel:

    $ grep -i mt7925 /boot/config-6.10.7-amd64
    # CONFIG_MT7925E is not set
    # CONFIG_MT7925U is not set

The Bluetooth functionality on the module that I have is provided by
a USB device with ID 13d3:3604, which needs a patch to add the device
ID [0]. It looks like this is in bluetooth-next and will probably be
in 6.12.

The firmware-mediatek package already ships firmware for the mt7925
driver:

    $ dpkg -L firmware-mediatek | grep mt7925
    /usr/lib/firmware/mediatek/mt7925
    /usr/lib/firmware/mediatek/mt7925/BT_RAM_CODE_MT7925_1_1_hdr.bin
    /usr/lib/firmware/mediatek/mt7925/WIFI_MT7925_PATCH_MCU_1_1_hdr.bin
    /usr/lib/firmware/mediatek/mt7925/WIFI_RAM_CODE_MT7925_1_1.bin

Ubuntu enabled the mt7925 driver some time ago [1].

Thanks!
