From fa98ddbdf7c804a8016488ccc98f8620149cac7b Mon Sep 17 00:00:00 2001
From: Raju Rangoju <Raju.Rangoju@amd.com>
Date: Mon, 20 Dec 2021 19:24:27 +0530
Subject: [PATCH 28/48] net: amd-xgbe: Alter the port speed bit range
commit 2d4a0b79dc6194048f7aa49c38d827cd5b7db6f1 upstream
Newer generation Hardware uses the slightly different
port speed bit widths, so alter the existing port speed
bit range to extend support to the newer generation hardware
while maintaining the backward compatibility with older
generation hardware.
The previously reserved bits are now being used which
then requires the adjustment to the BIT values, e.g.:
Before:
PORT_PROPERTY_0[22:21] - Reserved
PORT_PROPERTY_0[26:23] - Supported Speeds
After:
PORT_PROPERTY_0[21] - Reserved
PORT_PROPERTY_0[26:22] - Supported Speeds
To make this backwards compatible, the existing BIT
definitions for the port speeds are incremented by one
to maintain the original position.
