Subject: [virtio-dev] [PATCH v9 5/8] transport-ccw: Rename queue depth/size to other transports
Date: Tue, 28 Mar 2023 23:17:51 +0300	[thread overview]
Message-ID: <20230328201754.440974-6-parav@nvidia.com> (raw)
In-Reply-To: <20230328201754.440974-1-parav@nvidia.com>

max_num field reflects the maximum queue size/depth. Hence align name of
this field with similar field in PCI and MMIO transport to
max_queue_size.
Similarly rename 'num' to 'size'.

Fixes: https://github.com/oasis-tcs/virtio-spec/issues/163
Signed-off-by: Parav Pandit <parav@nvidia.com>
