This is done by toggling carrier during ndo_open/stop. Changes since V2: - introduce config_driver_disabled and helpers - schedule config change work unconditionally Jason Wang (3): virtio: rename virtio_config_enabled to virtio_config_core_enabled virtio: allow driver to disable the configure change notification virtio-net: synchronize operstate with admin state on up/down drivers/net/virtio_net.c | 64 ++++++++++++++++++++++++---------------- drivers/virtio/virtio.c | 59 ++++++++++++++++++++++++++++-------- include/linux/virtio.h | 11 +++++-- 3 files changed, 93 insertions(+), 41 deletions(-) -- 2.31.1
