hostapd: add additional network section to wpa_supplicant

[Florian Eckert]

Hello Community,

I have a openwrt system in mobile use.
That means I have a hostapd running as an access point for clients and 
at the same time a wpa_supplicant running to another access point as 
uplink.
So the router is client and access point at the same time on one radio.
My problem is that the access points for the uplink have different 
SSIDs.
I have to add several enabled uci wireless "wifi-iface" sections to 
connect to them.
The problem is now that I have running a wpa_supplicant process for each 
wifi-iface section.

I have seen that in the wpa_supplicant config you can add several 
network sections for each ssid, so I have only one wpa_supplicant 
process with x network sections.

The way I see it this is currently not possible with openwrt.
Does anyone have an idea how to implement this?
Or where do I have to start?

Kind regards

Florian
