^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 10) The Calxeda XGMAC Ethernet controllers are directly connected to the
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 11) internal machine "network fabric", which is set up, initialised and
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 12) managed by the firmware. So there are no PHY properties in this
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 13) binding. Switches in the fabric take care of routing and mapping the
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 14) traffic to external network ports.

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 28) Can point to at most 3 xgmac interrupts. The 1st one is the main
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 29) interrupt, the 2nd one is used for power management. The optional
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 30) 3rd one is the low power state interrupt.
