Subject: [virtio-dev] [PATCH v14 06/11] transport-mmio: Avoid referring to zero based index
Date: Wed, 19 Apr 2023 04:46:34 +0300	[thread overview]
Message-ID: <20230419014639.919458-7-parav@nvidia.com> (raw)
In-Reply-To: <20230419014639.919458-1-parav@nvidia.com>

VQ range is already described in the first patch in basic virtqueue
section. Hence remove the duplicate reference to it.

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

changelog:
v12->v13:
- corrected number to index
v11->v12:
- remove changes related to 'vq number'
v8->v9:
- added 'by' at two places
- replaced 'queue number' with 'vq number'

v6->v7:
- remove text around first vq as it is already covered in the basic
  virtqueues facility section
