Subject: [PATCH net-next 08/12] ethernet: enic: use eth_hw_addr_set()
Date: Fri, 15 Oct 2021 15:16:48 -0700 [thread overview]
Message-ID: <20211015221652.827253-9-kuba@kernel.org> (raw)
In-Reply-To: <20211015221652.827253-1-kuba@kernel.org>
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().
