Hello Daniel,
thanks for your feedback :+1:

The way I see it, we have to hook into here [1] for the sta mode.
Now I am not sure if this is also useful for other modes for example
mesh.
In the whole mac80211 layer there is no 'config_load' call.
All data settings are added via json.
So I do not have the new section 'wifi-credential' available to get the
additional network options from the json config.
I now only have the new uci list option ( I named it 'networks') for the
interface that points to the new 'wifi-credential' section to add an
additional network config section to the wpa_supplicant config.
May config would looks like this:
config wifi-iface 'wifinet2'
option device 'radio0'
option mode 'sta'
option encryption 'psk2+tkip'
option key 'nas21234'
option network 'nas2'
option ssid 'nas2'
option autoscan_periodic_interval '600'
list networks 'test1'
list networks 'test2'
config wifi-credential
option encryption 'psk2+tkip'
option key 'test1'
option ssid 'test1'
config wifi-credential
option encryption 'psk2+tkip'
option key 'test'
option ssid 'test'
The question is now who to iterate of the uci option 'networks' of the
'wifi-iface' to get the 'wifi-credential' and hand them over to the
wpa_supplicant_add_network [2] function.
In this function, all options are read from the config json object.
Is the procedure here that I have to implement this as in this Commit
[3].
And also have to update netifd as in this commits [5] [6].
So that we can use a new uci section wifi-credential via json?
Kind regards
Florian
