++ Say Y here if you want to use the Enhanced Stochastic Fairness
++ Queueing (ESFQ) packet scheduling algorithm for some of your network
++ 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
++ references to the SFQ algorithm).
++
++ 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.
