Subject: [virtio-dev] [PATCH v9 1/8] content: Add vq number text
Date: Tue, 28 Mar 2023 23:17:47 +0300	[thread overview]
Message-ID: <20230328201754.440974-2-parav@nvidia.com> (raw)
In-Reply-To: <20230328201754.440974-1-parav@nvidia.com>

Introduce vq number and its range so that subsequent patches can refer
to it.

Fixes: https://github.com/oasis-tcs/virtio-spec/issues/163
Signed-off-by: Parav Pandit <parav@nvidia.com>
---
changelog:
v8->v9:
- added inclusive when describing the vq number range
- skipped comment to put virtqueue number wording first because we
  prefer to use shorter vq number as much as possible
v5->v6:
- moved description close to introduction, it was in middle of
  queue data transfer description
v2->v3:
- new patch
