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

From: arinc9 . unal
Date: Sat Jun 17 2023 - 02:27:20 EST


From: Arınç ÜNAL <arinc.unal@xxxxxxxxxx>

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")
