Subject: [PATCH 9/9] miitool: Add option to scan mii buses
Date: Wed, 11 Dec 2013 12:41:17 +0100	[thread overview]
Message-ID: <1386762077-23205-10-git-send-email-s.hauer@pengutronix.de> (raw)
In-Reply-To: <1386762077-23205-1-git-send-email-s.hauer@pengutronix.de>

With the -s option all mii buses can be scanned for devices so
that they are available without doing network operations. Also,
now *all* phy devices on a mii bus can be examined, not only
the one attached to an ethernet device.
