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
|
|
