Subject: [patch] qla2xxx: use F/W calculated residual length.
Date: Tue, 1 Dec 2009 09:37:20 +0800 [thread overview]
Message-ID: <20091201013720.GA15068@joejin-pc.cn.oracle.com> (raw)
Hi,
When comp_status is CS_DATA_OVERRUN, residual length calculated by F/W,
but when comp_status is CS_COMMPLETE, residual length just set to residual
count, at here calculated residual length may via F/W?
Please review.
