From: Sudarsana Reddy Kalluru <sudarsana.kalluru@...ium.com>
To: <davem@...emloft.net>
CC: <netdev@...r.kernel.org>, <Ariel.Elior@...ium.com>
Subject: [PATCH net-next 4/4] qed: Add support for Unified Fabric Port.
This patch adds driver changes for supporting the Unified Fabric Port
(UFP). This is a new paritioning mode wherein MFW provides the set of
parameters to be used by the device such as traffic class, outer-vlan
tag value, priority type etc. Drivers receives this info via notifications
from mfw and configures the hardware accordingly.
