In addition,

Im running 2.4.21 kernel.

Just then, I was looking at the 2.6.11 kernel source
(net/core/skbuff.c) and found out that large chunk of the alloc_skb()
has been thrown out.

Can this be removed from 2.4.21 also ? I might go and check out why
its been removed.

Still waiting for some good answer tho .. :)

Cheers,
