Subject: [PATCH] add function wait_for_route_ok

Manually setuping nic through udev is not always done when

we want network access. Here add a function wait_for_route_ok to

wait and make sure the network is accesible

[v1 -> v2]:

Harald: don't use bash syntax

Add check for [ -n "$li" ] because `ip route show` will show nothing probably
