From 1c5d09d58748b74d8d03a9beadf691f8d9ec8622 Mon Sep 17 00:00:00 2001 From: Jakub Kicinski Date: Mon, 18 Oct 2021 07:29:25 -0700 Subject: [PATCH] ethernet: r8169: use eth_hw_addr_set() 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().
