[olsr-dev] Why are 1-hop routes with destination==gateway added

[Acinonyx]

Hello Erik,

this issue has been discussed before in this list.

The problem originates from quagga (zebra daemon) which doesn't accept 
as valid, routes with destination equal to gateway if they are not 
assigned to a p-t-p interface.

Either case, destintation ==gateway routes in olsr seems practically 
useless so I removed this part of code to work with quagga.

Regards,
Bill

P.S. A patch for 0.4.10 follows.
