MediaTek MT7961 (MT7921), MT7925 and MT7662 (MT76x2U) Wi-Fi firmware from linux-firmware
https://gitlab.com/kernel-firmware/linux-firmware
Commit: d5455717ead0affc6116809d8c6e71f95c63e8e1
Redistributable under LICENCE.mediatek, and mt7662*.bin under
LICENCE.ralink_a_mediatek_company_firmware; distributed as separate files, not
linked into any program.

mt7662.bin and mt7662_rom_patch.bin are requested without the mediatek/ prefix;
../mt7662.bin and ../mt7662_rom_patch.bin are links to them, as linux-firmware
installs them.
