I have a back to back setup.
I sometimes start with all modules unloaded, load them back
and bring up ipoib with a fixed ip address.

I then start opensm on one node, and try to ping one from another.
This does not work until I down and up ib0 on the node with
opensm running.

down and up on the other node does not help, which made me think
local mad handling is the culprit.
