PS2: You need to: 1- add a osmo_stream_srv_set_ip_dscp() API in libosmo-netif, which calls internally osmo_sock_set_dscp() on the stream socket 2- Use the new osmo_stream_srv_set_ip_dscp() from libosmo-netif in libosmo-sigtran's xua_accept_cb(), best place before the TCP/SCTP socket params are applied (see ss7_asp_apply_tcp_pars()).
