[Qemu-devel] [PATCH 1/4] vhost-user: fix multiple queue specification

[Maxime Coquelin <maxime.coquelin@redhat.com>]

The number of queues supported by the slave is queried with
message VHOST_USER_GET_QUEUE_NUM, not with message
VHOST_USER_GET_PROTOCOL_FEATURES.

Also, looking at master and slave implemntations, the payload
returned by the slave is the number of queue pairs supported
by the slave, not the number of queues.
