I always thought there was a single Ethernet controller on the A64 for
EMAC and GMAC and it is the PHY that is switchable. But several people
have told me that it is possible to run two simultaneous Ethernet net
connections on the A64 - one with the internal 100Mb PHY and one with
an external Gb PHY. So are these people confused or am I wrong and
there is a way to get two simultaneous interfaces on the A64?

I believe someone got simultaneous MACs going in the A20 about five
years ago. There was a blog talking about it, but the website is gone
now. It was a hobbyist trying to make a router based on the A20.
