7 title: Calxeda Highbank 10Gb XGMAC Ethernet controller

9 description: |
10 The Calxeda XGMAC Ethernet controllers are directly connected to the
11 internal machine "network fabric", which is set up, initialised and
12 managed by the firmware. So there are no PHY properties in this
13 binding. Switches in the fabric take care of routing and mapping the
14 traffic to external network ports.
