Subject: [PATCH v2 net-next 04/12] bnx2x: separate FCoE and iSCSI license initialization.
Date: Sun, 13 Nov 2011 14:47:21 +0200 [thread overview]
Message-ID: <1321188449-5822-5-git-send-email-dmitry@broadcom.com> (raw)
In-Reply-To: <1321188449-5822-1-git-send-email-dmitry@broadcom.com>
FCoE license info must be initialized at probe(), but
iSCSI at open().
