net: dsa: mt7530: add support for in-band link status

2022-09-23T10:58:37+00:00

Read link status from SGMII PCS for in-band managed 2500Base-X and 1000Base-X connection on a MAC port of the MT7531. This is needed to get the SFP cage working which is connected to SGMII interface of port 5 of the MT7531 switch IC on the Bananapi BPi-R3 board. While at it also handle an_complete for both the autoneg and the non-autoneg codepath. Signed-off-by: Daniel Golle Signed-off-by: David S. Miller

net: dsa: mt7530: get cpu-port via dp->cpu_dp instead of constant

2022-06-15T05:35:16+00:00

Replace last occurences of hardcoded cpu-port by cpu_dp member of dsa_port struct. Now the constant can be dropped. Suggested-by: Vladimir Oltean Signed-off-by: Frank Wunderlich Reviewed-by: Vladimir Oltean Reviewed-by: Florian Fainelli Signed-off-by: Jakub Kicinski

net: dsa: mt7530: partially convert to phylink_pcs

2022-04-12T08:33:15+00:00

Partially convert the mt7530 driver to use phylink's PCS support. This is a partial implementation as we don't move anything into the pcs_config method yet - this driver supports SGMII or 1000BASE-X without in-band.

net: dsa: mt7530: only indicate linkmodes that can be supported

2022-04-12T08:33:15+00:00

Now that mt7530 is not using the basex helper, it becomes unnecessary to indicate support for both 1000baseX and 2500baseX when one of the 803.3z PHY interface modes is being selected. Ensure that the driver indicates only those linkmodes that can actually be supported by the PHY interface mode. Tested-by: Marek Behún Signed-off-by: Russell King (Oracle) Signed-off-by: Paolo Abeni

net: dsa: mt7530: remove interface checks

2022-04-12T08:33:15+00:00

As phylink checks the interface mode against the supported_interfaces bitmap, we no longer need to validate the interface mode, nor handle PHY_INTERFACE_MODE_NA in the validation function. Remove these to simplify the implementation. Tested-by: Marek Behún Signed-off-by: Russell King (Oracle) Signed-off-by: Paolo Abeni

net: dsa: mt7530: populate supported_interfaces and mac_capabilities

2022-04-12T08:33:14+00:00

Populate the supported interfaces and MAC capabilities for mt7530, mt7531 and mt7621 DSA switches. Filling this in will enable phylink to pre-check the PHY interface mode against the the supported interfaces bitmap prior to calling the validate function, and will eventually allow us to convert to using the generic validation.

net: dsa: mt7530: manually set up VLAN ID 0

2021-08-25T10:09:31+00:00

The driver was relying on dsa_slave_vlan_rx_add_vid to add VLAN ID 0. After the blamed commit, VLAN ID 0 won't be set up anymore, breaking software bridging fallback on VLAN-unaware bridges. Manually set up VLAN ID 0 to fix this.

net: dsa: mt7530: drop untagged frames on VLAN-aware ports without PVID

2021-08-06T11:07:39+00:00

The driver currently still accepts untagged frames on VLAN-aware ports without PVID. Use PVC.ACC_FRM to drop untagged frames in that case. Signed-off-by: DENG Qingfang Signed-off-by: David S. Miller

net: dsa: mt7530: always install FDB entries with IVL and FID 1

2021-08-04T09:30:00+00:00

This reverts commit 7e777021780e ("mt7530 mt7530_fdb_write only set ivl bit vid larger than 1"). Before this series, the default value of all ports' PVID is 1, which is copied into the FDB entry, even if the ports are VLAN unaware. So `bridge fdb show` will show entries like `dev swp0 vlan 1 self` even on a VLAN-unaware bridge. The blamed commit does not solve that issue completely, instead it may cause a new issue that FDB is inaccessible in a VLAN-aware bridge with PVID 1. This series sets PVID to 0 on VLAN-unaware ports, so `bridge fdb show` will no longer print `vlan 1` on VLAN-unaware bridges, and that special case in fdb_write is not required anymore. Set FDB entries' filter ID to 1 to match the VLAN table. Signed-off-by: DENG Qingfang Reviewed-by: Vladimir Oltean Signed-off-by: David S. Miller

net: dsa: mt7530: set STP state on filter ID 1
