Fix incorrect sizeof operation being used for getting mac addr size. Found while compiling with arm64 clang. drivers/net/tap/rte_eth_tap.c:1410:40: error: argument to 'sizeof' in 'memcpy' call is the same pointer type 'struct ether_addr *' as the destination; expected 'struct ether_addr' or an explicit length [-Werror,-Wsizeof-pointer-memaccess] rte_memcpy(&pmd->eth_addr, mac_addr, sizeof(mac_addr)); ~~~~~~~~~~~~~~ ^~~~~~~~~~~~~~~~
