Subject: ethernet: netxen: use eth_hw_addr_set()
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=88e102e8777eccb569382d0cd289e88f0c0c6578;p=linux.git

ethernet: netxen: 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.

Invert the address into an array on the stack, then call
eth_hw_addr_set().
