+From 965d2b8068cb4479149058a9e9abf3c996d53fcc Mon Sep 17 00:00:00 2001
+From: Junxian Huang <huangjunxian6@hisilicon.com>
+Date: Wed, 22 Nov 2023 16:07:14 +0800
+Subject: [PATCH] libhns: Get dmac from kernel driver
+
+driver inclusion
+category: bugfix
+bugzilla: https://gitee.com/openeuler/kernel/issues/I8HZ7W
+
+--------------------------------------------------------------------------
+
+As dmac is already resolved in kernel while creating AH, there is no
+need to repeat the resolving in userspace. Prioritizes getting dmac
+from kernel driver, unless kernel driver didn't response one.
