The code is very similar, but the simple case can skip a few branches in the hot path. This improves PPS when 10KB mbufs are used. S/G is enabled on the Rx side by offload DEV_RX_OFFLOAD_SCATTER. S/G is enabled on the Tx side by offload DEV_TX_OFFLOAD_MULTI_SEGS. S/G is automatically enabled on the Rx side if the provided mbufs are too small to hold the maximum possible frame. To enable S/G in testpmd, add these args: --rx-offloads=0x2000 --tx-offloads=0x8000 Signed-off-by: Andrew Boyer <andrew.boyer@amd.com> Signed-off-by: R Mohamed Shah <mohamedshah.r@amd.com> |
