We could reproduce it easily using our user-space tool that creates 1000
mac-vlans, configures them, dumps routing tables, etc. But, we could
only reproduce it when we had the ixgbe ports unplugged. If they
were properly connected to a switch, we did not see any crashes.
My original email on 2/3/2014 has more details, and the thread that
follows has some info on debugging we did at the time.
We will be happy to test patches...
Thanks,
Ben
