I've got things set up and am hitting a problem.
My environment is OpenStack with two hypervisors. OpenStack attaches a
DHCP server to the virtual networks. I noticed that VMs local to the
DHCP server did not get a response. Remote VMs did get a response from
the DHCP server.
It seems the handling of broadcast packets skips output to any local ports.

for this flow to also output to table 33. I'm still working on the
