    "content": "The virtio features VIRTIO_NET_F_CSUM, VIRTIO_NET_F_HOST_TSO4\nand VIRTIO_NET_F_HOST_TSO6 are supported by the virtio PMD.\nBut they are missing in the supported feature set. And since\nbelow commit:\n\ncommit 4174a7b59d05 (\"net/virtio: improve Tx offload features negotiation\")\n\nVirtio PMD will announce the Tx offloading capabilities based\non the features read from the device. And virtio-user won't\nreport the features which are not in virtio-PMD's supported\nfeature set. So since that commit, virtio-user won't announce\nthe DEV_TX_OFFLOAD_UDP_CKSUM, DEV_TX_OFFLOAD_TCP_CKSUM and\nDEV_TX_OFFLOAD_TCP_TSO offloading capabilities even if the\nvhost backend supports them.\n\nThis patch adds these missing features, and virtio-user will\nreport them if the backend supports them.\n\nFixes: 142678d42959 (\"net/virtio-user: fix wrongly get/set features\")\nCc: stable@dpdk.org\n\nSigned-off-by: Tiwei Bie <tiwei.bie@intel.com>\n---\n drivers/net/virtio/virtio_ethdev.h | 5 ++++-\n 1 file changed, 4 insertions(+), 1 deletion(-)",
