Understood, but I see some corner cases.
For example, assume two bands AP hardware, 2.4GHz and 5GHz.
Previously:
- phy0 is 2.4Ghz
- phy1 is 5Ghz
- iw phy phy0 interface create wlan0 type managed
- iw dev wlan0 scan
=> will only scan 2.4Ghz
With single phy approach:
- phy0 is 2.4Ghz + 5Ghz concurrent
- # iw phy phy0 interface create wlan0 type managed
- # iw dev wlan0 scan
=> will scan both bands ?
- <starting from previous state>
- # iw phy phy0 interface create wlan1 type __ap
- # hostapd -i wlan1 <config>
- # iw dev wlan0 scan
=> what will happen then ?
Same goes for hostapd ACS, I assume specifying freqlist becomes
mandatory or we can't predict which band the AP will be on ?
