No one has to set the MAC address twice. This patch degrades
gracefully - if there is no NVS file on disk, no harm done.
This means a solution that only uses ifconfig or TESTMODE commands
before adding an interface will also work.

This patch only gives one the option to set the MAC address right when
the HW is initialized, without resorting to scripts or usermode
daemons. One has to simply put the NVS file on the filesystem and the
MAC will be read from there. I found this easier from an engineering
perspective.

Note that even without this patch its possible to set the MAC address
twice - use ifconfig, add a monitor interface and then use ifconfig
again to change the MAC.
