[riot-devel] C Bitfields and network_uint16_t

Hi Simon,
you can use network_uint16_t as integer by accessing it's u16 member, but
since bitfields are usually accessed using bit-arithmetics anyways I'm
wondering if it makes so much sense to use network_uint16_t, since they are
primarily used to warn about byteorder issues.
