I see some differences compared to the existing rules below.

>  country MY: DFS-FCC
>         (2402 - 2482 @ 40), (20)

Regulations say 2400 - 2500 MHz at 500mW.

>         (5170 - 5250 @ 80), (24), AUTO-BW

Regulations say 5150 - 5250 at 1W.

>         (5250 - 5330 @ 80), (24), DFS, AUTO-BW

Regulations say 5250 - 5350 at 1W with DFS and TPC required.
Since Linux doesn't have TPC support [1], this rule should be removed.

>         (5490 - 5650 @ 160), (24), DFS

Regulations say 5470 - 5650 at 1W with DFS and TPC required.
Since Linux doesn't have TPC support [1], this rule should be removed.

>         (5735 - 5835 @ 80), (24)

Regulations say 5735 - 5875 at 1W.

> +       (5925 - 6425 @ 320), (200 mW), NO-OUTDOOR

This part looks correct.

Could you update your patch to include these changes?
Or send a separate patch following this one to update the existing rules?


Thanks
ChenYu
