Sorry, a copy and paste error
Below is the ifconfig -A output, note I've updated llprio to 1 on the vlan
which now looks to send down the wire as prio=0 when testing on a client. Ref:
http://openbsd-archive.7691.n7.nabble.com/use-link0-on-vlan-4-to-force-the-vlan-priority-to-llprio-td339390.html.
With llprio=1 on the pppoe0 device I get the below
OpenBSD:

In the morning I'll try doing a packet capture on the DD-WRT device that works
plugged in to another machine to grab it's PADI packets.
