Errors can show here when you are sending traffic in at a rate higher than can
be handled, so it can be normal to see that in some cases.
First thing I would check is that you have your PMD(s) and qemu threads doing
the fwding core affinitised to different cores so they get the max amount of
cycles they can.
I would also check a simple phy-phy test to eliminate any test equipment/NIC
setup issues.
