Hello, I need to change auto-negotiate, speed and duplex for a port on my mt7620a-based device, but I'm not quite certain that I understand the structure here. When using ethtool on eth0 I always get ENODEV, apparently because priv->phy_dev is always NULL in fe_get_link_ksettings of drivers/net/ethernet/mtk/ethtool.c. But I'm being told that eth0 is only an internal device between the µC and the switch hardware, so it isn't even the one I need to change.
If this is true, then it looks like I will need to implement a get_port_link function for struct switch_dev_ops? Can anybody confirm this to be the case? Also, are there any examples aside from the Broadcom drivers? I have the mt7620 programmer's guide and it specifies the registers I need to change. Thanks, Daniel
