From 66908eff12627c3dd09b0e1f3801d57b425f2e23 Mon Sep 17 00:00:00 2001 From: Tiwei Bie Date: Fri, 21 Sep 2018 20:52:43 +0800 Subject: [PATCH] net/virtio: add missing supported features The virtio features VIRTIO_NET_F_CSUM, VIRTIO_NET_F_HOST_TSO4 and VIRTIO_NET_F_HOST_TSO6 are supported by the virtio PMD. But they are missing in the supported feature set. And since below commit: commit 4174a7b59d05 ("net/virtio: improve Tx offload features negotiation") Virtio PMD will announce the Tx offloading capabilities based on the features read from the device. And virtio-user won't report the features which are not in virtio-PMD's supported feature set. So since that commit, virtio-user won't announce the DEV_TX_OFFLOAD_UDP_CKSUM, DEV_TX_OFFLOAD_TCP_CKSUM and DEV_TX_OFFLOAD_TCP_TSO offloading capabilities even if the vhost backend supports them. This patch adds these missing features, and virtio-user will report them if the backend supports them.
