beware! linux-firmware has changed mt76 fw path about hcxdumptool HOT 2 CLOSED

Thanks for that information.
Usually I take the source directly from the Linux kernel tree (stable and mainline) to test patches.
In case of mt7921u monitor problem we (@morrownr) decided to collect this problems on upstream directly:
morrownr/USB-WiFi#260 (comment)
That's much better than handling this problem here:
https://github.com/morrownr/USB-WiFi/issues
or here:
https://github.com/ZerBea/hcxdumptool/issues

I noticed that there is/was work in progress
https://patchwork.kernel.org/project/linux-wireless/list/
also during the last past year:
https://lore.kernel.org/all/YapTmM3EztojTS9F@lore-desk/T/
https://patchwork.kernel.org/project/linux-wireless/patch/c61deba952e23bcfa98e28778bc11af524ad2f1e.1645832790.git.objelf@gmail.com/#24755669

The driver (kernel 6.6.2) is working fine (managed mode):

[120392.004344] mt7921u 1-9.3:1.3: WM Firmware Version: ____010000, Build Time: 20230526130958
[120393.638531] mt7921u 1-9.3:1.3 wlp22s0f0u9u3i3: renamed from wlan0

only monitor mode and frame injection failed.

from hcxdumptool.

Out of scope.
