OK good news here, the performance drop on the myri was caused by a
problem between the keyboard and the chair. After the reboot series,
I forgot to reload the firmware so the driver used the less efficient
firmware from the NIC (it performs just as if LRO is disabled).

That makes me think that I should try 3.8-rc2 since LRO was removed
there :-/

The only remaining issue really is the loopback then.
