Subject: [PATCH] net: dsa: b53: Improve flow control setup on BCM5301x

According to the Broadcom's reference driver flow control needs to be
|
|
enabled for any CPU switch port (5, 7 or 8 - depending on which one is
|
|
used). Current code makes it work only for the port 5. Use
|
|
dsa_is_cpu_port() which solved that problem.
