Subject: [PATCH v2] ep93xx-eth: check for zero MAC address on probe, not on device open
Date: Sun, 29 Nov 2009 00:57:00 +0100	[thread overview]
Message-ID: <200911290057.02109.florian@openwrt.org> (raw)

If we happen to have registered the driver without passing
a MAC address, we will print a zero MAC address and register
the interface with this invalid address, this is confusin. This
patch moves the checking of a valid ethernet address and the
generation of a random one down from the open function to
the probe function.
