Q: State of Linux RSTP support

Q: State of Linux RSTP support

According to Stephen Hemminger's presentation at
http://www.slideshare.net/shemminger/new-bridge (which seems to be the
most recent information available on the topic) the in-kernel bridging
code only provides STP. 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.

Any pointers?

There is https://git.kernel.org/cgit/linux/kernel/git/shemminger/rstp.git/
but it's 3 years old.  Don't know if Stephen has anything newer.
