Subject: [PATCH net-next 2/3] net: um: use eth_hw_addr_set()

From: Jakub Kicinski <[email-masked]>

Commit 406f42fa0d3c ("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 go through appropriate helpers.
