From 422c3107ed2cc6297f051109f3d4b6d855eaae14 Mon Sep 17 00:00:00 2001 From: "Yisen.Zhuang\\(Zhuangyuzeng\\)" Date: Sat, 23 Apr 2016 17:05:08 +0800 Subject: [PATCH] net: hns: add attribute reset-field-offset for dsaf node Add the subctrl reset offset for dsaf, this property is used to reset xge/ge ports for different dsaf. If this attribute is not present, default value 0 will be used. Signed-off-by: Daode Huang Signed-off-by: Yisen Zhuang Signed-off-by: David S.
