From 41edfff572d9ed0a9b8f8d136f2cfa213244746e Mon Sep 17 00:00:00 2001 From: Jakub Kicinski Date: Fri, 15 Oct 2021 15:16:48 -0700 Subject: [PATCH] ethernet: enic: 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. Use a zero'ed array on the stack, then call eth_hw_addr_set().
