[Qemu-devel] [PULL 06/11] vhost-user-scsi: add missing virtqueue_size pa

From: Paolo Bonzini
Subject: [Qemu-devel] [PULL 06/11] vhost-user-scsi: add missing virtqueue_size param
Date: Thu, 16 Nov 2017 12:59:21 +0100

From: Dariusz Stojaczyk <address@hidden>

Commit 5c0919d0 [1] introduced virtqueue_size parameter
for common virtio-scsi path, without updaing the vhost-user-scsi
code. vhost-user-scsi devices right now report size 0 for each vq.

This patch introduces virtqueue_size param to vhost-user-scsi,
that can now be set by the user. However, the most importantly, it
now has a default value of 128 (same as QEMU's virtio-scsi).

[1] 5c0919d0 ("virtio-scsi: Add virtqueue_size parameter
allowing virtqueue size to be set.")
