Subject: [PATCH] ib/ehca: fix in_wc handling in process_mad()
Date: Tue, 16 Feb 2010 09:59:50 +0100	[thread overview]
Message-ID: <20100216095950.15c6eb9d@alex-laptop> (raw)

If the caller does not pass a valid in_wc to process_mad(),
return MAD failure as it is not possible to generate a valid
MAD redirect response.
