But I wasn't speaking about power, I was speaking about channel bandwidth. You cannot fit a 40 MHz channel into the freq range 2483.5 - 2454. > >> + (2454 - 2483.5 @ 40), (N/A, 10), NO-INDOOR > > > > Same here. > > > >> + (5150 - 5250 @ 40), (N/A, 23), NO-OUTDOOR > >> + (5250 - 5350 @ 40), (N/A, 23), NO-OUTDOOR, DFS, PASSIVE-SCAN > >> + (5470 - 5725 @ 40), (N/A, 30), DFS, PASSIVE-SCAN > > > > Hm, actually so I had removed PASSIVE-SCAN from all entries > > as I had determined that this was only used for DFS purposes. > > As you can see in your case both have DFS so I'd leave only DFS. > > So essentially we can get rid of these: > > > > RRF_PASSIVE_SCAN = 1<<7, /* passive scan is required */ > > RRF_NO_IBSS = 1<<8, /* IBSS is not allowed */ > > > > What I noted was that PASSIVE-SCAN for example was only used for when > > we don't have DFS in STA and NO_IBSS when we don't have DFS in IBSS. > > > > So we can just stick to DFS flag, unless you are aware of other > > considerations for them.

We'll have to add the docs, this is just what what I determined from my own review on regulatory, with regulatory folks. I asked a "why" for each flag.
