[PATCH net-next v3 05/12] net: phy: nxp-c45-tja11xx: use get_features

From: Radu Pirea (NXP OSS)
Date: Tue Jun 27 2023 - 03:22:39 EST


PHY_BASIC_T1_FEATURES are not the right features supported by TJA1103
anymore.
For example ethtool reports:
[root@alarm ~]# ethtool end0
Settings for end0:
Supported ports: [ TP ]
Supported link modes: 100baseT1/Full
10baseT1L/Full

10baseT1L/Full is not supported by TJA1103 and supported ports list is
not completed. The PHY also have a MII port.

genphy_c45_pma_read_abilities implementation can detect the PHY features
and they look like this.
[root@alarm ~]# ethtool end0
Settings for end0:
Supported ports: [ TP MII ]
Supported link modes: 100baseT1/Full
Supported pause frame use: Symmetric
Supports auto-negotiation: No
Supported FEC modes: Not reported
Advertised link modes: 100baseT1/Full
Advertised pause frame use: Symmetric
Advertised auto-negotiation: No
Advertised FEC modes: Not reported
Speed: 100Mb/s
Duplex: Full
Auto-negotiation: off
master-slave cfg: forced master
master-slave status: master
Port: Twisted Pair
PHYAD: 1
Transceiver: external
MDI-X: Unknown
Supports Wake-on: g
Wake-on: d
Link detected: yes
SQI: 7/7
