From: Changchun Ouyang In non-SRIOV environment, VMDq RSS could be enabled by MRQC register. In theory, the queue number per pool could be 2 or 4, but only 2 queues are available due to HW limitation, the same limit also exists in Linux ixgbe driver. Signed-off-by:

Destroy corresponding device when a VHOST_USER_RESET_OWNER message is received, otherwise, the vhost-switch would still try to access vq of that device, which results to SIGSEG fault, and let vhost-switch crash in the end. Signed-off-by: Changchun Ouyang Signed-off-by: Yuanhan Liu ---

All queue pairs, including the default (the first) queue pair, are allocated dynamically, when a vring_call message is received first time for a specific queue pair. This is a refactor work for enabling vhost-user multiple queue; it should not break anything as it does no functional changes: we
