Yep, TXC is MAC-to-PHY for RGMII, but PHY-to-MAC for MII.

I believe this has a hard dependency on the driver patches, as a
failure to configure pin settings will cause the device to fail to probe?
Hence to avoid regressions, this has to wait one cycle...

In personal conversations with technical people, I call myself a hacker. But
when I'm talking to journalists I just say "programmer" or something like that.
