Then you will have the above test > result. ;-) Do you mean that combine patch 1 and patch 2 into one patch to support vlan stripping and bad checksum flag, Then also do the same work for patch 3 and patch 4 to support good checksum flag and enable IXGBE neon vector when DEV_RX_OFFLOAD_CHECKSUM is set?
Actually, the test results are achieved without patch 4, due to that testpmd does not check rxmode->offloads, it will call IXGBE NEON vector function directly. And this change is for the default config of l3fwd example.
