It will be pushed if I get no objections before 03/20/23. 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/kevintraynor/dpdk-stable This queued commit can be viewed at: https://github.com/kevintraynor/dpdk-stable/commit/5de7a11e063fdf703e930242617a556d79c2bed7 Thanks. Kevin --- >From 5de7a11e063fdf703e930242617a556d79c2bed7 Mon Sep 17 00:00:00 2001 From: Huisong Li Date: Fri, 10 Mar 2023 17:35:10 +0800 Subject: [PATCH] net/hns3: separate setting redirection table [ upstream commit a421cb93462932717f23c5d8342381726e547ba6 ] The settings of redirection table comes from the ethdev ops (like, dev_configure and rss_hash_update) and rte_flow API. For the ethdev ops, driver has to save it to rss_info::rss_indirection_tbl in hns3_hw structure so as to it can be restored when reset is triggered. While rte_flow API no need to use this field to save, they has a global RSS flow list to maintain all rules which can be used to restore the table during the reset phase.
