From 20981a1e6b708536493e10ba90016ae28a9f3749 Mon Sep 17 00:00:00 2001 From: Huazhong Tan Date: Fri, 16 Aug 2019 16:09:41 +0800 Subject: [PATCH] net: hns3: prevent unnecessary MAC TNL interrupt MAC TNL interrupt is used to collect statistic info about link status changing suddenly when netdev is running. But when stopping netdev, the enabled MAC TNL interrupt is unnecessary, and may add some noises to the statistic info. So this patch disables it before stopping MAC.
