[dpdk-dev] [PATCH v9 05/14] eal/pci: Consolidate pci address comparison APIs

This patch replaces pci_addr_comparison() and memcmp() of pci addresses by rte_eal_compare_pci_addr(). To compare PCI addresses, rte_eal_compare_pci_addr() doesn't use memcmp(). This is because sizeof(struct rte_pci_addr) returns 6, but actually this structure is like below. struct rte_pci_addr
