In esp_eth_test_apps.c: Add test of loopback functionality. Change speed/duplex/autonegotiation test - remove need to enable loopback (required for it to work on some phys supported by ESP-IDF) In Kconfig.projbuild: Add parameters to select which configuration is used - standard or custom. Add for custom configuration parameters to select MDC and MDIO pins (required to work with WESP-32 and other boards that use non-standard pin assignments). In esp_eth_test_common.c: Add code to support changes made in Kconfig In sdkconfig.ci.default_rtl8201: Change config which is used. Now custom is used and MDC is gpio 16, MDIO is gpio 17. Reuqired to work with WESP-32 In esp_eth_phy_802_3.h: Make 802.3 API public. In esp_eth_phy_802_3.c: Add loopback check in eth_phy_802_3_set_duplex(). Now ESP_ERR_INVALID_STATE is invoked on attempt to set duplex to half when loopback is enabled. Remove static property from esp_eth_phy_802_3_autonego_ctrl and esp_eth_phy_802_3_loopback. In esp_eth_phy_dm9051.c: Add dm9051_loopback() because DM9051 requires setting additional bit to enable auto-negotiation loopback for data to be received. Add dm9051_set_speed() which invokes ESP_ERR_INVALID_STATE on attempt to set speed to 10 Mbps when loopback is enabled because such speed configuration is unsupported. In esp_eth_phy_ksz80xx.c: Add ksz80xx_set_speed() which invokes ESP_ERR_INVALID_STATE on attempt to set speed to 10 Mbps when loopback is enabled because such speed configuration is unsupported. In esp_eth_phy_ksz8851snl.c: Change phy_ksz8851_set_duplex() to invoke ESP_ERR_INVALID_STATE on attempt to set duplex to half when loopback is enabled. In esp_eth_phy_dp83848.c, esp_eth_phy_rtl8201.c: Add autonego_ctrl implementation which prevents enabling autonegotiation when loopback is enabled. Add loopback implementation which disables autonegotiation prior to enabling loopback. In esp_eth_phy_lan87xx.c: Add autonego_ctrl implementation which prevents enabling autonegotiation when loopback is enabled. Add loopback implementation which disables autonegotiation prior to enabling loopback. Fix link indicating being down when loopback is enabled by force setting link up.
