From 937f599a1126545ec68f13b6c799231a5ee631b5 Mon Sep 17 00:00:00 2001 From: Grzegorz Siwik Date: Fri, 29 Mar 2019 15:08:30 -0700 Subject: [PATCH] i40e: VF's promiscuous attribute is not kept This patch fixes a bug where the promiscuous mode was not being kept when the VF switched to a new VLAN. Now we are config two times a promiscuous mode when we switch VLAN. Without this change when we change VF VLAN we still receive all the packets from previous VLAN and only unicast from new VLAN.
