RTSP is (should be) provided by a user space daemon, rtspd. However, none of the distributions I routinely use provide that daemon. Sourceforge has a project named rstpd but it seems to be inactive. A search for RSTP in the current git tree finds - - in net/bridge/br_netlink.c, a comment: /* Binary compatibility with old RSTP */ - - in net/bridge/br_private.h, an enum constant for struct net_bridge member stp_enabled: BR_USER_STP, /* new RSTP in userspace */ but nothing in, say, the Documentation folder.
