I'd expect there to be a limit on channels being within a single band on
a single "hardware"?
There are ath12k hardware supporting multiple band which need to be
registered under one mac80211_hw/wiphy. This design is to support such
hardware.
Oh OK, that was something that I didn't have in mind any more, or never
knew or paid attention to.
Would it work to leave the phy reporting pretty much as it is now, but add
a 'associated_peer_radios' list section, so that each phy could report the phys
associated with it? Then user-space, driver, mac80211 etc could look up the
other phys as needed to get a full picture?
At least with mtk 7996, it appears there will be 3 single-band phys can can be used
independently, but I assume when they have MLO support, those three will be logically
grouped.
Thanks,
