Hi,

Uh, sorry for the delay.

I don't remember, but quite likely we decided it was just not something
we could implement properly or so, and never supported it? Sorry.

Clearly the kernel does nothing at all with NL80211_RRF_PTMP_ONLY.

OTOH, doesn't AUTO-BW basically ignore the max bandwidth for a given
range anyway, seeing the code in reg_get_max_bandwidth_from_range()? So
just keeping it at 80 with AUTO-BW would still result in 160 being
usable? I think?
