Subject: [PATCH net-2.6 5/9] sfc: Change falcon_probe_board() to fail for unsupported boards
Date: Fri, 23 Apr 2010 23:26:46 +0100 [thread overview]
Message-ID: <1272061606.5520.18.camel@achroite.uk.solarflarecom.com> (raw)
In-Reply-To: <1272061459.5520.15.camel@achroite.uk.solarflarecom.com>
The driver needs specific PHY and board support code for each SFC4000
board; there is no point trying to continue if it is missing.
Currently unsupported boards can trigger an 'oops'.

Not speaking for my employer; that's the marketing department's job.
They asked us to note that Solarflare product names are trademarked.
