From 40173a2ec70c6386f5b342dfd612c26453a3f6b4 Mon Sep 17 00:00:00 2001 From: Fuyun Liang Date: Fri, 5 Jan 2018 18:18:18 +0800 Subject: [PATCH] net: hns3: fix for updating fc_mode_last_time commit a9c782822166 ("net: hns3: add support for set_pauseparam") adds set_pauseparam support for ethtool cmd, but forgets to update fc_mode_last_time when PFC mode is disabled in hclge_cfg_pauseparam(). The wrong fc_mode_last_time will be used to update flow control mode when lldpad has been running. As a result, when using the ethtool command "-a", user will get a wrong pause parameter. This patch adds the fc_mode_last_time update when PFC mode is disabled.
