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
connection?

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.
