DAARP to consider full channel bandwidth in channel selection 7.0.4

In previous implementations, DARRP did not consider channel bandwidth when selecting channels. In this enhancement, DARRP will also consider the radio bandwidth in its channel selection, adding support for 40, 80, and 160Mhz channel bandwidth.

To enable DAARP and support more channel bandwidth options:

This example changes the bandwidth in Radio1 from 20Mhz to 40Mhz, and changes Radio2 from 20Mhz to 80Mhz

config wireless-controller wtp-profile
  edit "433F"
    config platform
      set type 433F
      set ddscan enable
    end
    set handoff-sta-thresh 55
    set allowaccess https ssh
    config radio-1
      set band 802.11ax,n,g-only
        set channel-bonding 40MHz
        set darrp enable
        set arrp-profile "arrp-profile1"
    end
    config radio-2
      set band 802.11ax-5G
      set channel-bonding 80MHz
      set darrp enable
      set arrp-profile "arrp-profile2"
    end
    config radio-3
      set mode monitor
    end
  next
end

To verify the DARRP output from the managed FortiAP:

From the managed FortiAP, the DARRP output shows that the range in Radio1 is now 1 - 6 and in Radio2 is 36 - 161.
