-- Contains the Traffic Class byte of an IPv6 header.
-- 
-- This consists of the DSCP field as per
-- <https://www.rfc-editor.org/rfc/rfc2474#section-3 RFC 2474>,
-- and the ECN field as per
-- <https://www.rfc-editor.org/rfc/rfc3168#section-5 RFC 3168>.
-- 
-- It may be received using 'GI.Gio.Objects.Socket.socketReceiveMessage' over UDP sockets
-- (i.e. sockets in the @G_SOCKET_FAMILY_IPV6@ family with
-- @G_SOCKET_TYPE_DATAGRAM@ type). The message is not meant for sending. To set
-- Traffic Class field to be used in datagrams sent on a t'GI.Gio.Objects.Socket.Socket' use:
