Temporarily back out the last change, rev. 184.108.40.206.
The problem with it was that it swapped the relative order of IP
assignment and parent interface attachment. The present if_vlan
code gets certain flags from the parent, including those meaningful
to the upper layers. E.g., IP assignment to an interface with
IFF_BROADCAST goes somewhat differently from that to a non-broadcast
interface. Consequently, assigning IP before attaching the parent
results in a bogus or missing broadcast address on the vlan interface.
This bug is still here, but at least it won't be triggered by doing
both vlanX configuration steps, IP and vlan+vlandev, in a single
ifconfig invocation, which is usual to setting up vlans via rc.conf.
Work at the global issue is under way.
