Well, the problem actually is the next step. If I can requote my problem,
once I delete the said qdiscs and classes, I cannot reinstate the same.
The TBF qdisc returns saying " RTNETLINK : invalid parameter " I am
enclosing the iterations I am performing in this regard :

To throw in more light on the problem, one more thing I have found out is
that, this problem is seen only if I set the peakrate parameter in the TBF
qdisc !!! Else this works fine. A sample CBQ script on 2.2.12(RH 6.0) does
not have the peakrate in it, which works fine ;)
Hope this helps in attacking the problem further !
Thank you very much once again,
Vinay.
