Subject: [PATCH net-next 01/13] mlxsw: Use one enum for all registers that contain tunnel_port field

From: Amit Cohen <amcohen@...dia.com>

Currently SFN, TNUMT and TNPC registers use separate enums for
tunnel_port.

Create one enum with a neutral name and use it.
Remove the enums that are not currently required.

The next patches add two more registers that contain tunnel_port field,
the new enum can be used for them also.
