From 89a440932b6f2eb7fee78dbde05870e2b95e6151 Mon Sep 17 00:00:00 2001 From: "Yisen.Zhuang\\(Zhuangyuzeng\\)" Date: Sat, 23 Apr 2016 17:05:05 +0800 Subject: [PATCH] net: hns: add a new dsaf mode for debug port This patch adds a new dsaf mode named "single-port" mode for debug port. This mode only contains one debug port. This patch also changes the method of distinguishing the port type. Signed-off-by: Daode Huang Signed-off-by: Yisen Zhuang Signed-off-by: David S.
