Check on the correct return value from vringh_notify_enable_kern(). It returns false if more packets are available, not true. Signed-off-by: Sjur Br?ndeland <sjur.brandeland at stericsson.com> --- Hi, This patch applies to Rusty's virtio-next branch. Thanks, Sjur drivers/net/caif/caif_virtio.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git

From: Sjur Br?ndeland <sjur.brandeland at stericsson.com> Add wrappers for the host vrings to support loose coupling between the virtio device and driver. A new struct vringh_config_ops with the functions find_vrhs() and del_vrhs() is added to the virtio_device struct. This enables virtio drivers to manage virtio host rings without detailed knowledge of how the vrings are created and deleted. The function vringh_notify() is added so vringh clients can notify the other side th...

At the moment, if a virtio network device uses vrings with less than MAX_SKB_FRAGS + 2 entries, the device won't be functional. The following condition vq->num_free >= 2 + MAX_SKB_FRAGS will always evaluate to false, leading to TX timeouts. This patchset attempts this fix this bug, and to allow small rings down to 4 entries. The first patch introduces a new mechanism in virtio core -
