cbq2.1 
		
This release of CBQ (Class Based Queueing) implements many new features.
It implements Top-Level link-sharing as opposed to Ancestor-Only link
sharing as in the previous release.  It also implements Weighted-Round Robin
within scheduling priority levels.

Also implemented is a rather simplistic user-level scheduling daemon that
enables experimentation with creation of various link-sharing scenarios. The
CBQ scheduling module and the CBQ daemon implement a user/kernel interface
that allows for the creation/deletion of classes and the create/deletion
of simplistic packet filters.

Kernel Files:

usr/src/uts/common/inet/rm_class.c: Implements the CBQ link-sharing scheduler.
usr/src/uts/common/inet/cbqddi.c: Wrapper for CBQ module/driver for solaris
	device driver.
usr/src/uts/common/inet/cbq.c: Implements CBQ user/kernel interface for
	CBQ module.
usr/src/uts/common/inet/cbq_class.c: Implements the CBQ simplistic packet
	classifier.
usr/src/uts/common/inet/mi.c: utility routines for solaris inet drivers.
usr/src/uts/common/inet/mi.h: utility routine header files.
usr/src/uts/common/inet/pktsched.c: Prototype DLPI packet scheduler
	registration routines.
usr/src/uts/common/netinet/cbq.h: User/kernel packet scheduler interface.
usr/src/uts/common/netinet/rm_class.h: Packet scheduler header file.
usr/src/uts/common/netinet/rm_class_debug.h: Implement CBQ trace facility
	for Solaris.
usr/src/uts/common/netinet/pktsched.h: DLPI packet scheduler registration.

User level files:

usr/src/cmd/cmd-inet/usr.sbin/cbqd/cbqd.c: Implements simple user level
	daemon that parses a configuration file and runs the link-sharing
	structures.
usr/src/cmd/cmd-inet/usr.sbin/cbq/cbqd.h: header files defining functions
	in cbqif.c.
usr/src/cmd/cmd-inet/usr.sbin/cbq/cbq_config.c:  Routine to parse cbq
	configuration files.
usr/src/cmd/cmd-inet/usr.sbin/cbq/cbqif.c:  Routines to create classes and
	filters and pass to the kernel module.
usr/src/cmd/cmd-inet/usr.sbin/cbq/cbq.conf:
	Example cbq configuration file.

Bug Fixes:
=========
	- July, 1998 - several bugfixes related to link-sharing and
	  TCP flows.  Reported by Bob Lindel (llindel@isi.edu).
	  Copyright notices updated.

	- Dec 4th, 1997 reported by Sally Floyd <floyd@ee.lbl.gov>,
	  Link-sharing was temporarily broken.  Corrected setting of
	  the cutoff variable in rmc_updata_class_util.

	- Oct 13th, 1997, reported by Michael Speer <speer@eng.sun.com>,
	  calculation for offtime, maxidle incorrect.

	- Oct 3rd, 1997, reported by Richard Jones <rjones@imcl.com>:
	  rmc_delete_class removes the wrong class when there is two or more
	  classes in the same priority level.

	- Sept 12th, 1997, reported by Nick.Farrow@bt-sys.bt.co.uk.  
 	  netinet/rm_class.h: RM_POWER had been defined to be
	  (2 ^ RM_FILTER_GAIN) which is (2 XOR RM_FILTER_GAIN),
	  instead of 2 to the power of RM_FILTER_GAIN.

	- Sept 11th, 1997, reported by Michael Speer.  Fixed overlimit class
	  sleep problem. Classes using rmc_delay_action where sleeping to
	  short a period of time.
