From: Carlos Bilbao <cbilbao@xxxxxxxxxxxxxxxx> Initialize speed and duplex for virtio_net_config to UNKNOWN (mlx5_vdpa vDPA devices currently do not support VIRTIO_NET_F_SPEED_DUPLEX). Remove ioctl VHOST_VDPA_SET_CONFIG and its related logic as it is not supported; see: https://docs.oasis-open.org/virtio/virtio/v1.3/virtio-v1.3.html Carlos: vdpa/mlx5: Set speed and duplex of vDPA devices to UNKNOWN vdpa: Remove ioctl VHOST_VDPA_SET_CONFIG per spec compliance --- Changes since v1: Link: https://lkml.org/lkml/2024/8/29/1368 - Fix prefix of the first commit and add Reviewed-By tag. - Redo second commit completely: instead of attempting to add support to set configuration fields, remove ioctl and support entirely from vDPA implementations -- because it's not allowed by spec. Changes since v2: Link: https://lkml.org/lkml/2024/9/3/1407 - Fix first commit by changing 4 spaces for a tab. - In second commit, ENI is legacy and should keep set_config(). Change it to set_config_legacy() to avoid future confusion and erroneous implementations. --- drivers/vdpa/alibaba/eni_vdpa.c | 2 +- drivers/vdpa/ifcvf/ifcvf_main.c | 10 ---------- drivers/vdpa/mlx5/net/mlx5_vnet.c | 19 ++++++++++++------- drivers/vdpa/pds/vdpa_dev.c | 16 ---------------- drivers/vdpa/solidrun/snet_main.c | 18 ------------------ drivers/vdpa/vdpa.c | 16 ---------------- drivers/vdpa/vdpa_sim/vdpa_sim.c | 16 ---------------- drivers/vdpa/vdpa_sim/vdpa_sim.h | 1 - drivers/vdpa/vdpa_user/vduse_dev.c | 7 ------- drivers/vdpa/virtio_pci/vp_vdpa.c | 14 -------------- drivers/vhost/vdpa.c | 26 -------------------------- drivers/virtio/virtio_vdpa.c | 9 --------- include/linux/vdpa.h | 7 ++++--- include/uapi/linux/vhost.h | 8 ++++---- 14 files changed, 21 insertions(+), 148 deletions(-)
