Subject: [PATCH net-next v2 03/12] net: qmi_wwan: use dev_addr_mod()
Date: Thu, 21 Oct 2021 06:12:05 -0700 [thread overview]
Message-ID: <20211021131214.2032925-4-kuba@kernel.org> (raw)
In-Reply-To: <20211021131214.2032925-1-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.
Acked-by: Bjørn Mork <bjorn@mork.no>
