-    To ensure that vPMD is in the binary code, ensure that the option CONFIG_RTE_IXGBE_INC_VECTOR=y is in the configure file.
 
 Some constraints apply as pre-conditions for specific optimizations on bulk packet transfers.
 The following sections explain RX and TX constraints in the vPMD.

+To support UDP zero checksum, the zero and bad UDP checksum packet is marked as
