The flags are direct copy of the "unsigned int" in the network stream,
so the stream contains a 32 bits field encoded with the host endian.
- This is not reliable for stream betwen different architecture host
- For x86, the bits doesn't correspond to the documentation.
This patch add some precision in the documentation and put the bitfield
in the stream usig network butes order.
Warning: this patch can break compatibility with existing agents.
This patch should be backported in all version supporing SPOE
