Those first two patches need more thinking on my side. > netdev-linux: Fix offloads for IPv6 UDP packets. > dp-packet: Remove Linux specific L4 offloads. > dp-packet: Remove DPDK specific IP version. > dp-packet: Add OVS offloading API. > dp-packet: Expand offloads preparation helper. > dp-packet: Rework tunnel offloads. > dp-packet: Rework IP checksum offloads. > dp-packet: Rework L4 checksum offloads. > dp-packet: Rework TCP segmentation. > dp-packet: Remove direct access to DPDK offloads. > netdev-dpdk: Stop relying on vhost-user Tx flags.
