====================
wireless-next patches for v6.7

The second pull request for v6.7, with only driver changes this time.
We have now support for mt7925 PCIe and USB variants, few new features
and of course some fixes.

Major changes:

mt76

ath12k
 - read board data variant name from SMBIOS

wfx
 - Remain-On-Channel (ROC) support
