ETHADDR32_COPY

#define ETHADDR32_COPY	(		dst,

MEMCPY-like macro to copy to/from struct eth_addr's that are local variables or known to be 32-bit aligned within the protocol header.

ETHADDR16_COPY

#define ETHADDR16_COPY	(		dst,
			src
	)		SMEMCPY(dst, src, ETH_HWADDR_LEN)

MEMCPY-like macro to copy to/from struct eth_addr's that are no local variables and known to be 16-bit aligned within the protocol header.

eth_addr_cmp

#define eth_addr_cmp	(		addr1,
			addr2
	)		(memcmp((addr1)->addr, (addr2)->addr, ETH_HWADDR_LEN) == 0)
