      Both changes to the kernel, and to userland control applications are included
      in this checkin.  At present, these files are combined patches; I'll be
      separating out the Emulab specific additions/changes in the near future.
      The best resource (currently) for understanding the Linux traffic control
      mechanisms is at the Linux Diffserv project home page (under Documentation):
      The most noteworthy contributions I've made are the PLR module and DELAY
      module port and enhancement.  These two modules are classful (though they
      don't use classification filters) and can be chained together with other
      modules such as the Heirarchical Token Bucket (used for limiting bandwith).
      See: http://luxik.cdi.cz/~devik/qos/htb/
      Note that this checkin also includes the patches necessary to obtain
      Intermediate Queueing Devices (IMQ) and HTB control under iproute2+tc.  The
      IMQ devices allow the attachment of qdiscs on the incoming side of a real
      interface (can't do this without them). See: http://trash.net/~kaber/imq/
      The Linux Advanced Routing HOWTO is another good source of information:
