Subject: [PATCH net-next 12/12] ethernet: ixgb: use eth_hw_addr_set()
Date: Fri, 15 Oct 2021 15:16:52 -0700 [thread overview]
Message-ID: <20211015221652.827253-13-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.
Read the address into an array on the stack, then call
eth_hw_addr_set(). ixgb_get_ee_mac_addr() is used with
a non-nevdev->dev_addr pointer so we can't deal with the problem
inside it.
