From 662e382244fb29d8bf03113524a139541e10123f Mon Sep 17 00:00:00 2001 From: Ivan Malov Date: Thu, 11 Oct 2018 15:51:13 +0100 Subject: [PATCH 1/1] net/sfc: allow to query RSS key and HF when RSS is disabled If global RSS is not enabled in the multiqueue mode setting, it will not be possible to change RSS configuration. However, querying default RSS settings should be possible in any case since it may be needed by RTE flow API users to find out what RSS settings will be used by default for a flow rule with RSS action if custom RSS key and hash function choice are not specified.
