The rest are small fixes that I accumulated while reviewing the mbuf offload flags. On this last patch, it has the potential of breaking existing applications using the vhost library (OVS being impacted). I did not mark it for backport. Changes since v2: - kept behavior untouched (to avoid breaking ABI) and introduced a new flag to select the new behavior, Changes since v1: - dropped patch on net/tap, - added missing bits in example/vhost, - relaxed checks on VIRTIO_NET_HDR_GSO_ECN and VIRTIO_NET_HDR_GSO_UDP, -- David Marchand David Marchand (4): mbuf: mark old offload flag as deprecated net/virtio: do not touch Tx offload flags net/virtio: refactor Tx offload helper vhost: fix offload flags in Rx path doc/guides/prog_guide/vhost_lib.rst | 12 ++ doc/guides/rel_notes/release_21_05.rst | 6 + drivers/net/vhost/rte_eth_vhost.c | 2 +- drivers/net/virtio/virtio_rxtx.c | 7 +- drivers/net/virtio/virtio_rxtx_packed_avx.h | 2 +- drivers/net/virtio/virtio_rxtx_packed_neon.h | 2 +- drivers/net/virtio/virtqueue.h | 81 ++++---- examples/vhost/main.c | 44 ++--- lib/mbuf/rte_mbuf_core.h | 3 +- lib/vhost/rte_vhost.h | 1 + lib/vhost/socket.c | 5 +- lib/vhost/vhost.c | 6 +- lib/vhost/vhost.h | 14 +- lib/vhost/virtio_net.c | 185 ++++++++++++++++--- 14 files changed, 268 insertions(+), 102 deletions(-) -- 2.23.0
