* Tegra Hypervisor Network emulation
|
||
|
|
|
||
|
|
Required properties:
|
||
|
|
- compatible: Should be "nvidia,tegra-hv-net"
|
||
|
|
- ivc: Should contain a tupple containing a reference to the tegra hypervisor
|
||
|
|
node and an index of the IVC channel to use
|
||
|
|
|
||
|
|
Optional properties:
|
||
|
|
- mac-address: The MAC address to assign, if not available uses a random one.
|
||
|
|
- high-watermark-mult: High watermark multiplication factor for netif queue control.
|
||
|
|
default is 50. The network queue will be stopped when the number of queued skbs
|
||
|
|
reaches the 'high-watermark-mult' * 'the capacity in frames' is reached.
|
||
|
|
Note this is set at a very high limit for good throughput.
|
||
|
|
- low-watermark-mult: Low watermark multiplication factor for netif queue control.
|
||
|
|
default is 25. When the network queue is stopped and the amount of queued skbs
|
||
|
|
falls below the 'low-watermark-mult' * 'the capacity in frames' level the network
|
||
|
|
queue will be started. Note that high-watermark-mult must be higher than the
|
||
|
|
low-watermark-mult value.
|
||
|
|
- max-tx-delay-msecs: The maximum timeout value for transmits (in milliseconds.)
|
||
|
|
Any packet part of a send request that exceeds this value will be dropped.
|
||
|
|
|
||
|
|
Example:
|
||
|
|
tegra_hv_net {
|
||
|
|
compatible = "nvidia,tegra-hv-net";
|
||
|
|
status = "okay";
|
||
|
|
ivc = <&tegra_hv 2>;
|
||
|
|
};
