Details:

This was brought up on lwip-users by Bill Auerbach.
It would both speed up and decrease memory footprint by not using a packed
struct where we don't need it:

typedef u32_t ip_addr;

instead of

PACK_STRUCT_BEGIN
struct ip_addr {
  PACK_STRUCT_FIELD(u32_t addr);
} PACK_STRUCT_STRUCT;
PACK_STRUCT_END
