+.BR diffserv4

-+.BR diffserv-llt
-+|
+.BR diffserv3*
+]
+.br
+ Enables legacy interpretation of TOS "Precedence" field. Use of this
+preset on the modern Internet is firmly discouraged.
+.PP
-+.B diffserv-llt
-+.br
-+ Provides a "Latency-Loss Tradeoff" implementation with five tins:
-+.br
-+ Low Loss (TOS1, TOS2), 100% threshold, increased Codel target.
-+.br
-+ Best Effort (general), 100% threshold, normal Codel target & interval.
-+.br
-+ Low Latency (TOS4, TOS5, VA, EF), 100% threshold, reduced Codel interval.
-+.br
-+ Bulk (CS1), 6.25% threshold, normal Codel target & interval.
-+.br
-+ Net Control (CS6, CS7), 6.25% threshold, increased Codel target & interval.
-+.PP
+.B diffserv4
+.br
+ Provides a general-purpose Diffserv implementation with four tins:
