Subject: net/vlan: update to use modern iproute2 interface

This replaces the vlan setup code that previously used the old vconfig
binary with a new implementation using the iproute2 interface.

vconfig does not handle many of the newer setups. No automatic migration
path is provided, as altering the configuration is non-trivial.
