It will be pushed if I get no objections before 05/19/21. So please shout if anyone has objections. Also note that after the patch there's a diff of the upstream commit vs the patch applied to the branch. This will indicate if there was any rebasing needed to apply to the stable branch. If there were code changes for rebasing (ie: not only metadata diffs), please double check that the rebase was correctly done. Queued patches are on a temporary branch at: https://github.com/cpaelzer/dpdk-stable-queue This queued commit can be viewed at: https://github.com/cpaelzer/dpdk-stable-queue/commit/ea635e004f36361e38fa942cb10d83845b3946f9 Thanks. Christian Ehrhardt --- >From ea635e004f36361e38fa942cb10d83845b3946f9 Mon Sep 17 00:00:00 2001 From: Beilei Xing Date: Wed, 24 Feb 2021 10:09:00 +0800 Subject: [PATCH] net/i40evf: fix packet loss for X722 [ upstream commit c45bd78e07e9d4b5ffc29748b9b7d4127293597a ] When Tx queue number is more than Rx queue number, and RSS is enabled, there'll be packet loss with X722. The root cause is the lookup table is not configured correctly, since it uses VF's queue pair number but not Rx queue number.
