From bb50055ab49e5faf938fa7c6409ae26fd576ac57 Mon Sep 17 00:00:00 2001 From: Thomas Bogendoerfer Date: Wed, 15 Mar 2023 14:41:17 +0100 Subject: [PATCH] i825xx: sni_82596: use eth_hw_addr_set() [ Upstream commit 35e809dbd61106b1de959bb470c08c94fb369303 ] 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().
