Description Marcus Barrow 2008-09-12 15:05:48 EDT
This is a back port of a patch currently being submitted upstream.

It is a very simple 3 line fix to a problem reported by a major OEM.

This is been verified both via FW simulation of the FCP_RSP packet as
well as tested within the lab with a FC-jammer. It was also verified to fix
the original problem reported.

Add additional tightening of residual-count handling (originally
from commit 6acf8190025e9c4ea513d4084ff089d476112816) where the
driver should discard any lower SCSI-status during
firmware/transport residual-count mismatches.
