Subject: [PATCH] [RFC] cxacru: ignore ADSL routers
Date: Sat, 4 Sep 2010 14:01:07 +0200	[thread overview]
Message-ID: <201009041401.10034.linux@rainbow-software.org> (raw)
In-Reply-To: <4C81735E.3030903@simon.arlott.org.uk>

Ignore ADSL routers, which can have the same vendor and product IDs as ADSL
modems but should be driven by cx82310_eth driver.
