[PATCH] use ip command for vlan instead of vconfig

[Petr Lautrbach]

Hello,

attached patch removes using vconfig from initscripts.

vconfig is considered as deprecated and can be fully replaced by ip command
from iproute package.

I've tested this with common configurations but more tests are appropriated.

Regards,

Petr
