Was this tested on actual mt7925 hardware? You are right. I do not have mt7925 hardware to verify against. In v3, is_320mhz_supported() now checks is_mt7927() only, so mt7925 behavior is unchanged. > I don't think this should be copied from mt7996 as-is for mt7927.

The phy_cap_info[7] additions (NON_OFDMA_UL_MU_MIMO_320MHZ and MU_BEAMFORMER_320MHZ) are dropped in v3. Only the MCS/NSS maps and per-BW beamformee SS/sounding dimensions for 320MHz remain. Both changes are in v3, sent today. Best, Javier
