net: drivers: get ready for const 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 go through appropriate helpers. We will make netdev->dev_addr a const. Make sure local references to netdev->dev_addr are constant. Signed-off-by: Jakub Kicinski <kuba@kernel.org> Signed-off-by: David S. Miller <davem@davemloft.net>
