For i40e vector Tx path, if tx_offload is set as FAST_FREE_MBUF mode, no mbuf fast free operations are executed. To fix this, add mbuf fast free mode for vector Tx path. Furthermore, for i40e vector Tx path, if implement FAST_FREE_MBUF mode, it means per-queue all mbufs come from the same mempool and have refcnt = 1. Thus we can use bulk free of the buffers when mbuf fast free mode is enabled. For vector path in arm platform: In n1sdp, performance is improved by 18.4%; In thunderx2, performance is improved by 23%. For vector path in x86 platform: No performance changes.
