Subject: [PATCH 04/24] qla4xxx: Use IDC_CTRL bit1 directly instead of AF_83XX_NO_FWDUMP flag.
Date: Mon, 16 Dec 2013 06:49:34 -0500	[thread overview]
Message-ID: <1387194594-29817-5-git-send-email-vikas.chaudhary@qlogic.com> (raw)
In-Reply-To: <1387194594-29817-1-git-send-email-vikas.chaudhary@qlogic.com>

From: Vikas Chaudhary <vikas.chaudhary@qlogic.com>

Removed AF_83XX_NO_FWDUMP flag and directly checking IDC_CTRL bit1
while taking minidump, to check for graceful reset.
