| 7 | title: Calxeda Highbank 10Gb XGMAC Ethernet controller |
| 8 | |
| 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. |
