Merge branch 'dev_addr-direct-writes' 

Jakub Kicinski says:

====================
net: remove direct netdev->dev_addr writes

Commit 406f42fa0d ("net-next: When a bond have a massive amount
of VLANs...") introduced a rbtree for faster Ethernet address look
up. To maintain netdev->dev_addr in this tree we need to make all
the writes to it got through appropriate helpers.

This series contains top 5 conversions in terms of LoC required
to bring the driver into compliance.
====================
