Subject: [patch net-next 8/9] mlxsw: spectrum: Mark unused ports using NULL
Date: Mon, 22 Feb 2016 19:32:03 +0100 [thread overview]
Message-ID: <1456165924-14399-9-git-send-email-jiri@resnulli.us> (raw)
In-Reply-To: <1456165924-14399-1-git-send-email-jiri@resnulli.us>
From: Ido Schimmel <idosch@mellanox.com>
When splitting and unsplitting we'll destroy usable ports on the fly, so
mark them using a NULL pointer to indicate that their local port number
is free and can be re-used.
