Subject: [PATCH net-next 1/7] ethernet: constify references to netdev->dev_addr in drivers
Date: Wed, 13 Oct 2021 13:44:29 -0700 [thread overview]
Message-ID: <20211013204435.322561-2-kuba@kernel.org> (raw)
In-Reply-To: <20211013204435.322561-1-kuba@kernel.org>
This big patch sprinkles const on local variables and
function arguments which may refer to netdev->dev_addr.
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.
Some of the changes here are not strictly required - const
is sometimes cast off but pointer is not used for writing.
It seems like it's still better to add the const in case
the code changes later or relevant -W flags get enabled
for the build.
No functional changes.
Signed-off-by: Jakub Kicinski <kuba@kernel.org>

This patch is on the big side, but I figured time is better
invested in splitting up the patches which actually make
code changes.
