IPADDR_WORDALIGNED_COPY_FROM_IP4_ADDR_T

#define IPADDR_WORDALIGNED_COPY_FROM_IP4_ADDR_T	(		dest,
			src )

Value:

SMEMCPY(dest, src, sizeof(ip4_addr_t))

MEMCPY-like copying of IP addresses where addresses are known to be 16-bit-aligned if the port is correctly configured (so a port could define this to copying 2 u16_t's) - no NULL-pointer-checking needed.

IPADDR_WORDALIGNED_COPY_TO_IP4_ADDR_T

#define IPADDR_WORDALIGNED_COPY_TO_IP4_ADDR_T	(		dest,
			src )

Value:

MEMCPY-like copying of IP addresses where addresses are known to be 16-bit-aligned if the port is correctly configured (so a port could define this to copying 2 u16_t's) - no NULL-pointer-checking needed.
