[PATCH] bug in default interface number computation

[Guillaume Rousse <Guillaume.Rousse@inria.fr>]

[-- Attachment #1: Type: text/plain, Size: 543 bytes --]

As previously explained, the network-bridge script tries to
automatically find the default network interface number with the
following ligne:
vifnum=${vifnum:-$(ip route list | awk '/^default / { print $NF }' | sed
's/^[^0-9]*//')}

However, this fails on mandriva, because the parsed line is:
default via 193.55.250.126 dev eth0  metric 10

Attached patch fix this issue.

BTW, that's the second time I'm sending it, I've had no answer sofar. If
 this is not the recommanded way to declare problems and send correction
patches, just tell me.
