This driver is used for the Ethernet switch integrated into LS1028A NXP. Felix on LS1028A has 4 front panel ports and two internal ports, I/O to/from the switch is done through an ENETC Ethernet interface. The 4 front panel ports are available as Ethernet interfaces and can be used with the typical network commands like tftp.

This doesn't work for me. Seems like felix_init() is called before any ports are added via dsa_port_probe().
struct dsa_port_pdata *port_pdata = dsa_port_get_pdata(pdev);struct phy_device *phy = port_pdata->phy;/* Set up MAC registers */out_le32(base + FELIX_GMII_CLOCK_CFG(port_pdata->index),FELIX_GMII_CLOCK_CFG_LINK_1G);out_le32(base + FELIX_GMII_MAC_IFG_CFG(port_pdata->index),FELIX_GMII_MAC_IFG_CFG_DEF);felix_start_pcs(pdev, &priv->imdio);if (phy) {phy->supported &= supported;phy->advertising &= supported;phy_config(phy);
I've noticed because my PHY was never configured.
