Re: [Linphone-developers] PATCH: oRTP QOS/DSCP support

[Nicholas J Humfrey]

I have done a little bit of investigating and it looks like DSCP goes  
in the "Traffic Class" field of the IPv6 headers - this is 8-bit like  
the TOS field in IPv4 header - so I imagine it is treated the same.  
Code:

setsockopt(fd, IPPROTO_IPV6, IPV6_TCLASS, &tclass, sizeof(tclass));
