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

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

|
|
ethernet@0{
|
|
compatible = "hisilicon,hns-nic-v1";
|
|
ae-name = "dsaf0";
|
|
port-id = <0>;
|

local-mac-address = [a2 14 e4 4b 56 76];

};
