1 Hisilicon Network Subsystem NIC controller
4 - compatible: "hisilicon,hns-nic-v1" or "hisilicon,hns-nic-v2".
5 "hisilicon,hns-nic-v1" is for hip05.
6 "hisilicon,hns-nic-v2" is for Hi1610 and Hi1612.
7 - ae-name: accelerator name who provides this interface,
8 is simply a name referring to the name of name in the accelerator node.
9 - port-id: is the index of port provided by DSAF (the accelerator). DSAF can
10 connect to 8 PHYs. Port 0 to 1 are both used for adminstration purpose. They
11 are called debug ports.
13 The remaining 6 PHYs are taken according to the mode of DSAF.
15 In NIC mode of DSAF, all 6 PHYs are taken as ethernet ports to the CPU. The
16 port-id can be 2 to 7. Here is the diagram:

25 In Switch mode of DSAF, all 6 PHYs are taken as physical ports connect to a
26 LAN Switch while the CPU side assume itself have one single NIC connect to
27 this switch. In this case, the port-id will be 2 only.

38 - local-mac-address: mac addr of the ethernet interface
43 compatible = "hisilicon,hns-nic-v1";
46 local-mac-address = [a2 14 e4 4b 56 76];
