Subject: [PATCH net 0/3] net: dsa: lantiq_gswip: SGMII/2500BASE-X and flow-control fixes
Date: Mon, 7 Sep 2026 15:48:15 +0200 [thread overview]
Message-ID: <20260907134818.16670-1-havran.jan@email.cz> (raw)
This series fixes three issues in the lantiq_gswip / mxl-gsw1xx DSA driver
found while bringing up a MaxLinear GSW145 over SGMII on a Marvell
Armada 7040 board, with the switch CPU port running 2500BASE-X and the
user ports at 1000BASE-T.
Patch 1 reorders the SerDes NCO clock-rate setup ahead of the SGMII shell
reset. Without it, only the rate the switch was left at by the straps or
the boot loader links up; the other rate comes up but forwards no traffic.
Patch 2 adds the missing SPEED_2500 case to gswip_port_set_speed(); without
it the CPU port was forced to 10 Mbps at 2.5G link-up.
Patch 3 corrects the GSWIP_MDIO_PHY_FCONTX_EN field value (a typo present
since the original vrx200 driver).
Tested on GSW145 hardware only. The register values are backed by the
public GSW145 data sheet and by the driver's own field encoding; the
xRX200/xRX300 data sheets are not public.
