From f96818a7cc864ac612c157b5c5e8c57c4b3e0136 Mon Sep 17 00:00:00 2001 From: Yunsheng Lin Date: Sat, 10 Mar 2018 11:29:28 +0800 Subject: [PATCH] net: hns3: fix for loopback failure when vlan filter is enable When vlan ctag filter is enabled, the loopback selftest fails because loopback selftest does not support vlan. This patch fixes it by disabling the vlan ctag filter when runnig loopback selftest. Signed-off-by: Yunsheng Lin Signed-off-by: Peng Li Signed-off-by: David S.
