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.

ETHADDR32_COPY

#define ETHADDR32_COPY	(		dst,
			src
	)		SMEMCPY(dst, src, ETH_HWADDR_LEN)

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.
