From 80645dc0ffb7361726374bcc7bfc29337e8a385d Mon Sep 17 00:00:00 2001 From: Vikas Chaudhary Date: Mon, 16 Dec 2013 06:49:34 -0500 Subject: [PATCH] [SCSI] qla4xxx: Use IDC_CTRL bit1 directly instead of AF_83XX_NO_FWDUMP flag. Removed AF_83XX_NO_FWDUMP flag and directly checking IDC_CTRL bit1 while taking minidump, to check for graceful reset.
