Subject: Re: [PATCH] lpfc : add module parameter that allows adapter	instances to avoid attachment
Date: Thu, 26 Mar 2009 16:37:06 -0400	[thread overview]
Message-ID: <49CBE772.80304@emulex.com> (raw)
In-Reply-To: <1238098747.3342.54.camel@localhost.localdomain>

The oem requirement we have explicitly states not to use the unbind interface
(we proposed unbind at first as well).

The issue is what happens on the link while we are bound for that short
amount of time. It confuses the things on the other side of the link.
There's a secondary driver that ends up binding to the adapters we exclude,
and the things on the other side only expected to see the second driver.
