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/e
Hello Daniel,
Thanks for your help!

Hello,
I'm still fairly new to Ethernet drivers and there are a lot of
interesting pieces. What I need help with is understanding MDIO -->
(R)MII vs direct I/O to the MAC (e.g., via ioread32, iowrite32). Why is
there not always a struct mii_bus to talk to this hardware? Is it
because the PHY an
ds me to the question of what "GSW"
means? This is the name of the hardware that has the PIAC register, but
nowhere in the data sheet or programming guide can I find a definition.
Thanks,
Daniel

Hello,
Although I'm new to the entire Ethernet / *MII subsystem and I haven't
touched DSA yet, I've recently had to add some of this functionality to
the older OpenWRT drivers for swconfig control over the ports. René, do
you have an actual datasheet or programming guide for the mt7530? I
