Andrew Boyer e86a6fcc7c net/ionic: add optimized non-scattered Rx/Tx
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
