Looked at other drivers implementing this callback and here are the results:

[wil6210] wil_cfg80211_change_bss(): does exactly the same thing.
[wilc1000] change_bss(): worse! it accepts everything and does nothing.
[rtl8723bs] cfg80211_rtw_change_bss(): same. just an empty callback.

OK, though I guess other drivers being bad doesn't mean this one should
be :)

Sure. I am on your team in this. Can you recommend a plan of attack here? Should we add a mechanism to expose what BSS parameter changes the driver can handle similar to what is used for struct station_info::bss_params?

If this patch means Infineon is (mildly) regaining interest in upstream
wifi development let's not discourage them.

Fair. I didn't mean to discourage. I just think to meaningfully
contribute upstream people should follow the list. And even review other
people's patches. I've been meaning to make that more of a requirement,
since I can't possibly meaningfully review everything I now need to
merge.

Yeah. It's a bit of a tough spot I reckon.

I do watch the
linux-wireless list on occasion but I am a bit lost on your remark. What
do you mean by tree tags. You mean the "wifi:" prefix? But then I am
confused about the "subject prefix" remark.

Oh, well I guess terminology:

Ack.
