peoplez,

I have added support for tg3 on batching. I see equivalent performance
improvement for pktgen as i did with e1000 when using gige. 
I have only tested on two machines (one being a laptop which does
10/100Mbps). Unfortunately in both cases these are considered to be in
the class of  "buggy" tg3s (which take a longer code path).

To the tg3 folks - can you double check if am off on something?
I have split a few things that you may like as well.
I havent upgraded the tree - it is still circa 2.6.22-rc4 based; at some
point i will sync with Daves net-26

Anyone who has tg3 based hardware: I would appreciate any testing and
results ...

The git tree is at:
git://git.kernel.org/pub/scm/linux/kernel/git/hadi/batch-lin26.git
but i have attached the patch in case you just wanna stare.

cheers,
jamal
