Each call to the AVX2 vector burst receive function makes at least one pass through the function's inner loop, loading 256 bytes of completion descriptors and copying 8 rte_mbuf pointers regardless of whether there are any packets to be received. Unidirectional forwarding performance is improved by about 3-4% if we ensure that at least one packet can be received before entering the inner loop.
