From 07f8e94011d7d14d4633f076bae6e341fea5076e Mon Sep 17 00:00:00 2001 From: Jian Shen Date: Fri, 19 Jan 2018 14:41:11 +0800 Subject: [PATCH] net: hns3: add ethtool -p support for fiber port Add led location support for fiber port. The led will keep blinking when locating. Signed-off-by: Jian Shen Signed-off-by: Peng Li Signed-off-by: David S.
