Subject: IB/mlx4: Set traffic class in AH

From: Maor Gottlieb <[email protected]>

commit af4295c117b82a521b05d0daf39ce879d26e6cb1 upstream.

Set traffic class within sl_tclass_flowlabel when create iboe AH. Without this the TOS value will be empty when running VLAN tagged traffic, because the TOS value is taken from the traffic class in the address handle attributes.
