Subject: staging: unisys: use eth_hw_addr_set()
Patch-mainline: v5.16-rc1
Git-commit: 13898e9341824f8d96cb37e5f36eb1828e9f2e63
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.
