[dpdk-dev] [PATCH] eal: fix compilation without VFIO

[Shahaf Shuler <shahafs@mellanox.com>]

a compilation error occurred when compiling with CONFIG_RTE_EAL_VFIO=n

== Build lib/librte_eal/linuxapp/eal
  CC eal_vfio.o
/download/dpdk/lib/librte_eal/linuxapp/eal/eal_vfio.c:1535:1: error: no
previous prototype for 'rte_vfio_dma_map' [-Werror=missing-prototypes]
 rte_vfio_dma_map(uint64_t __rte_unused vaddr, __rte_unused uint64_t
iova,

/download/dpdk/lib/librte_eal/linuxapp/eal/eal_vfio.c:1542:1: error: no

 rte_vfio_dma_unmap(uint64_t __rte_unused vaddr, uint64_t __rte_unused

As there is no use for those dummy functions without VFIO removing them
completely.
