Subject: [PATCH net v6 2/6] net: dsa: mt7530: fix trapping frames on non-MT7621 SoC MT7530 switch

From: Arınç ÜNAL <arinc.unal@...nc9.com>

All MT7530 switch IP variants share the MT7530_MFC register, but the
current driver only writes it for the switch variant that is integrated in
the MT7621 SoC. Modify the code to include all MT7530 derivatives.

Fixes: b8f126a8d543 ("net-next: dsa: add dsa support for Mediatek MT7530 switch")
