pktgen IPSEC 0/4

This is a set of patches that add ipsec functionality to pktgen. I have lost these patches before - but they are now fully recovered and well tested. Robert has glanced at the patches and seems to have no qualms with them. I am soliciting for any feedback because i would like to push them for 2.6.23 when Dave opens his tree.

[I think i may have figured out how the cool cats send their series of patches using git patch-format but i am not sure i can trust my lil soldier's config to do the right thing. So i will do them manually. I am climbing up the git ladder folks, one step at a time!].

cheers,
