Subject: [PATCH net-next v2 1/9] net: switchdev: add SET_SWITCHDEV_OPS helper
Date: Wed, 28 Jun 2017 22:29:54 +0200	[thread overview]
Message-ID: <1498681802-2897-2-git-send-email-simon.horman@netronome.com> (raw)
In-Reply-To: <1498681802-2897-1-git-send-email-simon.horman@netronome.com>

Add a helper to allow switchdev ops to be set if NET_SWITCHDEV is configured
and do nothing otherwise. This allows for slightly cleaner code which
uses switchdev but does not select NET_SWITCHDEV.
