[ninux-dev] Dubbio su JSON for networks: phy0 vs radio0

radio0 comes from the UCI configuration section name while phy0 comes
from the driver in the kernel. The physical device associated with a
wireless interface in UCI may be configured using the phy attribute, for
example:

config wifi-device 'radio0'
    ...
    option phy 'phy0'
This is how you configure multiple radios on a device. You may also use
the MAC address using the macaddr attribute.

I am not sure how this is for non-mac80211 drivers.
