Subject: [PATCH net 2/6] qed: Assign UFP TC value to vlan priority in UFP mode.

From: Sudarsana Reddy Kalluru <skalluru@...vell.com>

In the case of Unified Fabric Port (UFP) mode, switch provides
the traffic class (TC) value to be used for the traffic.
Configure hardware to use this TC value for vlan priority.
