[PATCH net-next v2 04/15] net: dsa: mt7530: rename mt753x_bpdu_port_fw enum to mt753x_to_cpu_fw

From: Arınç ÜNAL via B4 Relay
Date: Mon Apr 22 2024 - 03:17:25 EST

From: Arınç ÜNAL <arinc.unal@xxxxxxxxxx>

The mt753x_bpdu_port_fw enum is globally used for manipulating the process
of deciding the forwardable ports, specifically concerning the CPU port(s).
Therefore, rename it and the values in it to mt753x_to_cpu_fw.

Change FOLLOW_MFC to SYSTEM_DEFAULT to be on par with the switch documents.
