Subject: net: bcmgenet: Add a shutdown callback
Git-commit: d9f45ab9e671166004b75427f10389e1f70cfc30
Patch-mainline: v5.5-rc1
References: jsc#SLE-7772

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.
