Subject: fddi: defxx,defza: use dev_addr_set()
Patch-mainline: v5.16-rc1
Git-commit: 1e9258c389ee58b34238abaa600c10270b081af8
References: jsc#PED-1565

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 got through appropriate helpers.
