Subject: [PATCH 04/15] wireless: ath6kl: use eth_hw_addr_set()
Date: Mon, 18 Oct 2021 16:50:10 -0700	[thread overview]
Message-ID: <20211018235021.1279697-5-kuba@kernel.org> (raw)
In-Reply-To: <20211018235021.1279697-1-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.

Do the special encoding on the stack, then copy the address.
