+	  devices or as a leaf discipline for a classful qdisc such as HTB or
+	  CBQ (see the top of <file:net/sched/sch_esfq.c> for details and

+	  This is an enchanced SFQ version which allows you to control some
+	  hardcoded values in the SFQ scheduler.
+
+	  ESFQ also adds control of the hash function used to identify packet
+	  flows. The original SFQ discipline hashes by connection; ESFQ add
+	  several other hashing methods, such as by src IP or by dst IP, which
+	  can be more fair to users in some networking situations.
