From d9f45ab9e671166004b75427f10389e1f70cfc30 Mon Sep 17 00:00:00 2001 From: Florian Fainelli Date: Tue, 15 Oct 2019 10:36:24 -0700 Subject: [PATCH] net: bcmgenet: Add a shutdown callback Make sure that we completely quiesce the network device, including its DMA to avoid having it continue to receive packets while there is no software alive to service those.
