Subject: [PATCH net 2/2] net: dsa: mt7530: fix port mirroring for MT7988 SoC switch
Date: Sat, 13 Apr 2024 16:01:40 +0300 [thread overview]
Message-ID: <20240413-b4-for-net-mt7530-fix-mirroring-to-local-port-and-mt7988-v1-2-476deff8cc06@arinc9.com> (raw)
In-Reply-To: <20240413-b4-for-net-mt7530-fix-mirroring-to-local-port-and-mt7988-v1-0-476deff8cc06@arinc9.com>
The "MT7988A Wi-Fi 7 Generation Router Platform: Datasheet (Open Version)
v0.1" document shows bits 16 to 18 as the MIRROR_PORT field of the CPU
forward control register. 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")
