6 years agonet: implement ECN handling, rfc6040 style fd/propagate-DSCP-bits
Florent Daigniere [Sat, 23 Feb 2019 20:50:04 +0000 (21:50 +0100)] 
net: implement ECN handling, rfc6040 style

To decide whether we should use the compatibility mode or the normal
mode with a peer, we use the handshake messages as a signaling channel.

If we receive the expected ECN bits, it most likely means they're
running a compatible version.

Fixed port overwrite issue on kernels without ipv6

Fixed an issue in CreateBind for Linux:
If ipv6 was not supported the error code would be
correctly identified as EAFNOSUPPORT and ipv4 binding attempted.
However the port would be set to 0,
which results in the subsequent create4 call requesting
a random port rather than the one provided to CreateBind.
