This is a prototype patch to enable sending TCP packets with pktgen. The
original motivation is to test TCP GSO with xen-netback/netfront, but I'm not
sure about how the checksum should be set up, and also someone should verify the
GSO settings I'm using.

What's the point of sending TCP packets since you don't establish a TCP

I guess they want to test checksumming and aggregation, things like that.

The other side is of course going to spew reset packets back at the
pktgen machine.

Yes, I just want to stress the driver, not the TCP stack on the other end? Netback/front doesn't handle UDP GSO, so to test TCP GSO we need to fed it with TCP packets. It would be good if someone can advise me how to setup checksum and GSO bits.
