Subject: [virtio-dev] [PATCH v9 7/8] virtio-net: Avoid duplicate receive queue example
Date: Tue, 28 Mar 2023 23:17:53 +0300	[thread overview]
Message-ID: <20230328201754.440974-8-parav@nvidia.com> (raw)
In-Reply-To: <20230328201754.440974-1-parav@nvidia.com>

Receive queue number/index example is duplicate which is already defined
in the Setting RSS parameters section.

Hence, avoid such duplicate example and prepare it for the subsequent
patch to describe using receive queue handle.

Fixes: https://github.com/oasis-tcs/virtio-spec/issues/163

 The device MUST determine the destination queue for a network packet as follows:
 \begin{itemize}
 \item Calculate the hash of the packet as defined in \ref{sec:Device Types / Network Device / Device Operation / Processing of Incoming Packets / Hash calculation for incoming packets}.
-\item If the device did not calculate the hash for the specific packet, the device directs the packet to the receiveq specified by \field{unclassified_queue} of virtio_net_rss_config structure (value of 0 corresponds to receiveq1).
-\item Apply \field{indirection_table_mask} to the calculated hash and use the result as the index in the indirection table to get 0-based number of destination receiveq (value of 0 corresponds to receiveq1).

 \item If the destination receive queue is being reset (See \ref{sec:Basic Facilities of a Virtio Device / Virtqueues / Virtqueue Reset}), the device MUST drop the packet.
