Reading PHY register

[PeterR]

I need to dump the Ethernet's PHY registers (LAN8710) for diagnostics & debug.

esp_eth_driver_t contains the element esp_eth_mediator_t mediator which has member phy_reg_read
Unfortunately the esp_eth_driver_t type is private. We get the void * cast esp_eth_handle_t.

How do I gain access to the PHY interface? I could expose esp_eth_driver_t but would rather not edit the IDF for obvious reasons.

After you create the MAC instance by esp_eth_mac_t *mac = esp_eth_mac_new_esp32(&mac_config);

then you can read PHY register just by mac->read_phy_reg
