+Subject: ethernet: constify references to netdev->dev_addr in drivers
+
+From: Jakub Kicinski <kuba@kernel.org>
+
+[ Upstream commit 766607570becbd26cab6d66a544dd8d0d964df5a ]
+
+This big patch sprinkles const on local variables and
+function arguments which may refer to 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.
+
+Some of the changes here are not strictly required - const
+is sometimes cast off but pointer is not used for writing.
+It seems like it's still better to add the const in case
+the code changes later or relevant -W flags get enabled
+for the build.
+
+No functional changes.
