Subject: [PATCH 02/14] iscsi tcp: bidi capable
Date: Thu, 5 Mar 2009 14:45:56 -0600 [thread overview]
Message-ID: <12362859702687-git-send-email-michaelc@cs.wisc.edu> (raw)
In-Reply-To: <12362859693831-git-send-email-michaelc@cs.wisc.edu>
From: Pete Wyckoff <pw@padd.com>
Mark iscsi_tcp as being capable of bidirectional transfers. The
bsg interface checks this bit before attempting any bidirectional
commands.
