[dpdk-dev] [PATCH 1/5] ixgbe: avoid compiler error when RTE_IXGBE_INC_VECTOR=y and RTE_LIBRTE_IXGBE_RX_ALLOC_BULK_ALLOC=n

[Cunming Liang]

The vpmd RX routine won't be used if RTE_LIBRTE_IXGBE_RX_ALLOW_BULK_ALLOC is not defined or its condition check fail.
The case RTE_LIBRTE_IXGBE_RX_ALLOC_BULK_ALLOC=n and RTE_IXGBE_INC_VECTOR=y may exist
when choose to use standard RX and optimized TX(ixgbe_xmit_pkts_vec/ixgbe_xmit_pkts_simple).
