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. > > -Srikanth
