...support GSO with udp tunnel and possible other encapsulations. This yeilds a significant perfromance improvement (still testing remote checksum code). An addition extension that is unfinished (due to still testing for any side-effects) is checksum passthrough to support drivers that set CHECKSUM_COMPLETE. This would eliminate the need for guests to compute the software checksum. This series only takes care of virtio net. I have addition patches for the host side (vhost and tap/macvtap as well as qemu), but wanted to get feedback on the general approach first. Vladislav Yasevich (6): virtio-n...
