From c0087473b7918d790771c873f0e63afb381ad5c2 Mon Sep 17 00:00:00 2001 From: Jian Shen Date: Thu, 12 Mar 2020 15:11:06 +0800 Subject: [PATCH 014/283] net: hns3: clear port base VLAN when unload PF mainline inclusion from mainline-v5.6-rc1 commit 59359fc8a2f7af062777692e6a7aae73483729ec category: cleanup bugzilla: https://gitee.com/src-openeuler/kernel/issues/I8EJ0A Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=59359fc8a2f7af062777692e6a7aae73483729ec -------------------------------- Currently, PF missed to clear the port base VLAN for VF when unload. In this case, the VLAN id will remain in the VLAN table. This patch fixes it.
