From 198e745083b960d167bd769e2f81818c835f68b8 Mon Sep 17 00:00:00 2001 From: Heinrich Kuhn Date: Fri, 10 Jul 2020 16:28:46 +0200 Subject: [PATCH] net/nfp: fix RSS hash configuration reporting Prior to this fix the NFP PMD implementation of the .rss_hash_conf_get callback did not propagate the current hardware state of rss_hf back up to the caller. Users of the hash_conf_get callback would receive an incorrect representation of what the RSS configuration currently is in hardware.
