[PULL 16/66] vhost-user: Make RESET_DEVICE a per device message

Posted by Michael S. Tsirkin 2 years, 5 months ago

From: Tom Lonergan <tom.lonergan@nutanix.com>

A device reset is issued per device, not per VQ. The legacy device reset
message, VHOST_USER_RESET_OWNER, is already a per device message. Therefore,
this change adds the proper message, VHOST_USER_RESET_DEVICE, to per device
messages.
