Some adaption work is + here to make the drivers can use the old ones or the new ones. + But suppose the target is to let all the NICs support the new APIs + and then remove the old ones. + So, in driver layer, we can begin to support the new ones and remove + the old ones. + Eight new commands are added: + Rx test commands: + 1. testpmd > show port rx_offload capabilities + 2. testpmd > show port rx_offload configuration + 3. testmpd > port config rx_offload on|off + 4. testpmd > port rxq rx_offload on|off + Tx test commands: + 1. testpmd > show port tx_offload capabilities + 2. testpmd > show port tx_offload configuration + 3. testmpd > port config tx_offload on|off + 4. testpmd > port txq tx_offload on|off + +Prerequisites +============= + +1.
