From 7287c63e986fe1a51a89f4bb1327320274a7a741 Mon Sep 17 00:00:00 2001 From: Eddie Wai Date: Mon, 16 May 2011 11:13:18 -0700 Subject: [SCSI] bnx2i: Fixed packet error created when the sq_size is set to 16 The number of chip's internal command cell, which is use to generate SCSI cmd packets to the target, was not initialized correctly by the driver when the sq_size is changed from the default 128. This, in turn, will create a problem where the chip's transmit pipe will erroneously reuse an old command cell that is no longer valid. The fix is to correctly initialize the chip's command cell upon setup.
