From 4c4a5686c4e7475ab16fdaa4da375e43810da978 Mon Sep 17 00:00:00 2001 From: Yan Markman Date: Thu, 12 Jul 2018 13:54:14 +0200 Subject: [PATCH] net: mvpp2: use RSS only when using multi-queue mode Since RSS only applies when we have per-cpu rx queues, it should only be enabled when the driver is configured to make use of multi-queue mode.
