From 30ebc576d7773c7d8b53fa7941c2c56e488589fd Mon Sep 17 00:00:00 2001 From: Jian Shen Date: Sat, 23 Feb 2019 17:22:16 +0800 Subject: [PATCH] net: hns3: enable VF VLAN filter for each VF when initializing For revision 0x21, the switch of VF VLAN filter is per function. It's necessary to enable VF VLAN filter for each VF when initializing. Otherwise, VF will be able to receive broadcast packets with unknown VLAN when PF enters promisc mode.
