From f409d0ed87d2721e1099ce36266e98c5aea2d486 Mon Sep 17 00:00:00 2001 From: Nikolay Aleksandrov Date: Mon, 12 Oct 2015 21:47:05 +0200 Subject: bridge: vlan: move back vlan_flush Ido Schimmel reported a problem with switchdev devices because of the order change of del_nbp operations, more specifically the move of nbp_vlan_flush() which deletes all vlans and frees vlgrp after the rx_handler has been unregistered. So in order to fix this move vlan_flush back where it was and make it destroy the rhtable after NULLing vlgrp and waiting a grace period to make sure noone can see it.
