From d4a16052bccdd695982f89d815ca075825115821 Mon Sep 17 00:00:00 2001 From: Aya Levin Date: Sun, 13 Sep 2020 18:05:40 +0300 Subject: net/mlx5e: Fix VLAN create flow When interface is attached while in promiscuous mode and with VLAN filtering turned off, both configurations are not respected and VLAN filtering is performed. There are 2 flows which add the any-vid rules during interface attach: VLAN creation table and set rx mode. Each is relaying on the other to add any-vid rules, eventually non of them does. Fix this by adding any-vid rules on VLAN creation regardless of promiscuous mode.
