A couple of my tests are failing with this patchset.  A simple port
test is failing and IPv4 routing test is failing.

The port test is simple: just connect a port on DUT to a port on
another system and assign an IP address to each port and verify IP
connectivity.  I have this:

   DUT:sw1p1 (11.0.0.1/24) <-----------> host1:eth0 (11.0.0.2/24)

The IPv4 routing tests is a bit more complicated to setup.  I'm using
OSPF, but I'm not seeing full routes formed in the topology, so I
suspect OSPF hellos aren't getting thru.

Please fix find/fix these issues and send v3.  I don't want any git
bisect issues when running tests.  Thanks.
