I have a fix for the trace you have below, but it has nothing to do
with no traffic. I'll send it out shortly.
Which protocol are you using (ipv4 or ipv6)? Have you setup a
bridge device containing the ports you wish to switch network
traffic. Without a bridge device, DSA will by default treat each
port as a separate port. The other thing that gets people is the
ethernet interface connected to the DSA switch must be up _before_
bringing up any of the switch ports.
