how to have only one hostapd instance?

[Carlito Nueno]

Hi all,

I am running openwrt 17.01.0 and hostapd v2.7-devel. I have two
radios, 2.4 ghz and 5 ghz.

There are two hostapd instances running. How can I have only one
hostapd instance to control both radios. Reason being, I want to have
band steering that's built into hostap. This requires to have only one
hostapd instance, correct?

/var/run/wifi-phy1.pid -B /var/run/hostapd-phy1.conf

/var/run/wifi-phy0.pid -B /var/run/hostapd-phy0.conf


Thanks!
