Subject: [PATCH 2/3] qla2xxx: Fix response queue count for Target mode.
Date: Wed, 15 Feb 2017 15:37:20 -0800 [thread overview]
Message-ID: <1487201841-28846-3-git-send-email-himanshu.madhani@cavium.com> (raw)
In-Reply-To: <1487201841-28846-1-git-send-email-himanshu.madhani@cavium.com>
From: Michael Hernandez <michael.hernandez@cavium.com>
Target mode initialization was not calculating response
queue values correctly resulting into one less MSI-X vector.
Fixes: 093df73 ("scsi: qla2xxx: Fix Target mode handling with Multiqueue changes.")
