Subject: ethernet: sis190: use eth_hw_addr_set()
Patch-mainline: v5.16-rc1
Git-commit: f60e8b06e0cc00c03c775a6b6f186782c5c8df8a
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.

Read the address into an array on the stack, then call
eth_hw_addr_set().
