From f12098ce9b43e1a6fcaa524acbd90f9118a74c0a Mon Sep 17 00:00:00 2001 From: Geetha sowjanya Date: Thu, 18 Mar 2021 19:45:47 +0530 Subject: octeontx2-pf: Clear RSS enable flag on interace down RSS configuration can not be get/set when interface is in down state as they required mbox communication. RSS enable flag status is used for set/get configuration. Current code do not clear the RSS enable flag on interface down which lead to mbox error while trying to set/get RSS configuration.
