It will be pushed if I get no objections before 02/28/23. 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/2f00c06957fc89f7a3a483d118ef5fcef558b847 Thanks. Kevin --- >From 2f00c06957fc89f7a3a483d118ef5fcef558b847 Mon Sep 17 00:00:00 2001 From: Huisong Li Date: Tue, 31 Jan 2023 21:02:57 +0800 Subject: [PATCH] net/hns3: remove useless code when destroy valid RSS rule [ upstream commit 546031ba551485c3e3aa57c3698975c2852cbef1 ] When all rules are flushed the hw::rss_info::conf::func set to RTE_ETH_HASH_FUNCTION_MAX and hw::rss_info::conf::queue set to NULL which indicates no flow rules is issued. See: commit eb158fc756a5 ("net/hns3: fix config when creating RSS rule after flush"). Actually, the way determining whether there are rules has been changed by walking the flow RSS list. See: commit 705a50800334 ("net/hns3: fix RSS filter restore"). In addition, the rte_flow_action_rss from user isn't saved to 'conf' in hw->rss_info now. So this code can be removed.
