Subject: [PATCH] i825xx: sni_82596: use eth_hw_addr_set()
References: bsc#1012628
Patch-mainline: 6.2.8
Git-commit: f38373345c65529639a01fba3675eb8cb4c579c3

[ Upstream commit f38373345c65529639a01fba3675eb8cb4c579c3 ]

netdev->dev_addr is now const, we can't write to it directly.
Copy scrambled mac address octects into an array then eth_hw_addr_set().

Fixes: adeef3e32146 ("net: constify netdev->dev_addr")
