Subject: [PATCH v3 net-next 01/16] linkmode: introduce linkmode_intersects()
Date: Mon, 20 Jul 2020 21:08:00 +0300 [thread overview]
Message-ID: <20200720180815.107-2-alobakin@marvell.com> (raw)
In-Reply-To: <20200720180815.107-1-alobakin@marvell.com>
Add a new helper to find intersections between Ethtool link modes,
linkmode_intersects(), similar to the other linkmode helpers.
