In case we will get regulatory request with rule where max_bandwidth_khz is set to 0 handle this case as a special one. If max_bandwidth_khz == 0 we should calculate maximum available bandwidth base on all frequency contiguous rules. In case we need auto calculation we just have to set: country PL: DFS-ETSI (2402 - 2482 @ 40), (N/A, 20) (5170 - 5250 @ AUTO), (N/A, 20) (5250 - 5330 @ AUTO), (N/A, 20), DFS (5490 - 5710 @ 80), (N/A, 27), DFS This mean we will calculate maximum bw for rules where AUTO (N/A) were set, 160MHz (5330 - 5170) in example above. So we will get: (5170 - 5250 @ 160), (N/A, 20) (5250 - 5330 @ 160), (N/A, 20), DFS In other case: country FR: DFS-ETSI (2402 - 2482 @ 40), (N/A, 20) (5170 - 5250 @ AUTO), (N/A, 20) (5250 - 5330 @ 80), (N/A, 20), DFS (5490 - 5710 @ 80), (N/A, 27), DFS We will get 80MHz (5250 - 5170): (5170 - 5250 @ 80), (N/A, 20) (5250 - 5330 @ 80), (N/A, 20), DFS Base on this calculations we will set correct channel bandwidth flags (eg. IEEE80211_CHAN_NO_80MHZ). We don't need any changes in CRDA or internal regulatory.
