[PATCH v2 1/8] netconfig: Decouple from station state
by Tim Kourt
Instead of relying on station state changed signal, netconfig
introduces three new API calls to configure, re-configure and
reset the network configurations. The owner of netconfig object
is responsible for initiating the re-configuration of the device
depending on its state.

So I don't think this is necessary. The mac address right now will be
static for the duration of netconfig's lifetime. So providing the mac
at configure time (and maybe teardown) is sufficient.
