Currently, the MT7530 DSA subdriver configures +bits 0 to 2 of the CPU forward control register which breaks the port +mirroring feature for the MT7988 SoC switch. + +Fix this by using the MT7531_MIRROR_PORT_GET() and MT7531_MIRROR_PORT_SET() +macros which utilise the correct bits. + +Fixes: 110c18bfed41 ("net: dsa: mt7530: introduce driver for MT7988 built-in switch") +Signed-off-by: Arınç ÜNAL <arinc.unal@arinc9.com> +Acked-by: Daniel Golle <daniel@makrotopia.org> +Signed-off-by: David S.
