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. 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.
