Indeed, this path is not compliant with the Virtio specification, so could cause problems with some host implementations. Since Marvin has introduced the in-order path, we have a good replacement for simple Tx and so we think it is better to remove it than disabling it by defaul Maxime Coquelin (4): net/virtio: remove simple Tx path net/virtio: improve Tx offload features negotiation net/virtio: don't use simple Rx if TCP LRO or VLAN strip net/virtio: improve offload check performance drivers/net/virtio/virtio_ethdev.c | 49 ++++++++++++++++------ drivers/net/virtio/virtio_ethdev.h | 3 -- drivers/net/virtio/virtio_pci.h | 4 +- drivers/net/virtio/virtio_rxtx.c | 74 ++++++--------------------------- drivers/net/virtio/virtio_rxtx_simple.c | 67 ----------------------------- drivers/net/virtio/virtio_rxtx_simple.h | 49 ---------------------- drivers/net/virtio/virtio_user_ethdev.c | 1 - 7 files changed, 51 insertions(+), 196 deletions(-) -- 2.14.4
