Basically using by point-to-point mode we could save some addresses and
make auto-configuration of the WDS links much simpler :)

Since we're not planning to use bridging we have to dedicate a /30 subnet
to each p2p link.  Whilst it's possible to add the same IP used on wlan0
to e.g. wlan0wds0 and then add a host route for neighbouring router it's
a bit of a cludge and Zebra seems to fall over using this configuration
(perhaps that's a bug with zebra though!).

In the case when a WDS link is really a point-to-point between 2 routers
it would seem kinda sensible for it to run in point-to-point mode :)
