Subject: [PATCH v2 net-next 4/9] sunvnet: add driver stats for ethtool support
Date: Tue,  7 Feb 2017 14:12:57 -0800	[thread overview]
Message-ID: <1486505582-76823-5-git-send-email-shannon.nelson@oracle.com> (raw)
In-Reply-To: <1486505582-76823-1-git-send-email-shannon.nelson@oracle.com>

Since we're collecting some stats in the driver code, let's support use
of the ethtool driver stats facility in both sunvnet and ldmvsw.
