virtio: vhost checksum problem for ipv6
When checksum is enable for IPv6, it erroneously set the flag VNET_BUFFER_F_OFFLOAD_IP_CKSUM. That flag is meant for ip4 packets only. Type: fix Ticket: VPP-1857 Signed-off-by: Steven Luong <sluong@cisco.com> Change-Id: Id03b2937bfa34e2a9b50a36aafe0700bad7fb95e (cherry picked from commit f78294d8468f156e066e7e69aab3a1b285810c3a)
