[LARTC] ESFQ patch problem

[Anil Kumar]

 I applied esfq patch to kernel then I have applied
 iproute2-2.2.4-now-ss001007-esfq.diff to
    patch iproute2 (tc utility, iproute2-ss010824)
 source: http://www.ssi.bg/~alex/esfq/
 
 But whenever I try to add esfq qdisc with parameter it says it donot
 know the qdisc i.e esfq.
 
  tc qdisc add dev eth0 parent 1:13 handle 13: esfq perturb 34 quantum
 1514 depth 25 divisor 23 limit 34534 hash src
 
 Unknown qdisc "esfq", hence option "perturb" is unparsable
 
 but if I donot specify any parameters i.e
 tc qdisc add dev eth0 parent 1:13 handle 13: sfq perturb 3
 
qdisc esfq 13: [Unknown qdisc, optlen=24]
 is added.
 
 Is their some incompatibility between kernel and tc utility ?
 I am working in a customized kernel with minimum functionality
 (embedded applications).Is some thing missing?
