From 8edc2285b7285c5fbffe438dc8113260d3e76656 Mon Sep 17 00:00:00 2001 From: Jian Shen Date: Thu, 20 Dec 2018 11:52:04 +0800 Subject: [PATCH] net: hns3: don't restore rules when flow director is disabled When user disables flow director, all the rules will be disabled. But when reset happens, it will restore all the rules again. It's not reasonable. This patch fixes it by add flow director status check before restore fules.
