[dpdk-dev] [PATCH 0/2] virtio fix false offload claims

While doing code for Hyper-V, noticed that the virtio driver was
confused about receive versus transmit offloads.  The virtio
checksum offload is L4 (TCP/UDP) only, not IPv4. Also, TSO
and LRO are not the same.

This may break some program that was assuming it was getting offloads
that it wasn't.

Stephen Hemminger (2):
  virtio: don't falsely claim to do IP checksum
  virtio: don't claim to support LRO
