[6.0]pkt_sched: Fix sch_sfq vs tcf_bind_filter oops

Solution Verified - Updated -


  • In packet scheduler function 'SFQ qdisc', the SFQ class has no 'bind_tcf' method. Then, if a filter added with the classid parameter to the SFQ, kernel will hang-up because the 'bind_tcf' pointer is null. Additionally, a similar problem concerning 'leaf' method exists.
