It will be pushed if I get no objections before 03/01/23. 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://git.dpdk.org/dpdk-stable/log/?h=22.11-staging This queued commit can be viewed at: https://git.dpdk.org/dpdk-stable/commit/?h=22.11-staging&id=36d6105f51c1a99385bf118968304777f38e1c7e Thanks. Xueming Li --- >From 36d6105f51c1a99385bf118968304777f38e1c7e Mon Sep 17 00:00:00 2001 From: Huisong Li Date: Tue, 31 Jan 2023 21:02:53 +0800 Subject: [PATCH] net/hns3: refactor set RSS hash algorithm and key interface Cc: Xueming Li [ upstream commit 88347111eb53bc54c598dde81715a06ca1dbd132 ] The hns3_rss_set_algo_key() is used to set RSS hash algorithm and key to hardware. The maximum execution time of the command sent to the firmware is proportional to the length of the key. However, now this times is fixed, which isn't good for key expansion. In addition, hash algorithm comes from rss_info::hash_algo maintained in the driver, which also isn't good for the usage of this function. Interface is updated to get hash algorithm and key length as input parameters.
