From d466effe282ddbab6acb6c3120c1de0ee1b86d57 Mon Sep 17 00:00:00 2001 From: Jakub Kicinski Date: Wed, 6 Oct 2021 18:06:55 -0700 Subject: of: net: add a helper for loading netdev->dev_addr 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. There are roughly 40 places where netdev->dev_addr is passed as the destination to a of_get_mac_address() call. Add a helper which takes a dev pointer instead, so it can call an appropriate helper. Note that of_get_mac_address() already assumes the address is 6 bytes long (ETH_ALEN) so use eth_hw_addr_set(). Signed-off-by: Jakub Kicinski Signed-off-by: David S.
