From 54f2d8d6ca99a3e24efc9c8b055bbcbe0b583227 Mon Sep 17 00:00:00 2001 From: Jakub Kicinski Date: Wed, 13 Oct 2021 13:44:30 -0700 Subject: ethernet: make eth_hw_addr_random() use dev_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.
