|
|
device, found in Marvel Armada family of SOCs.
|

It uses Marvell Usermode SDK
|
|
(`MUSDK <https://github.com/MarvellEmbeddedProcessors/musdk-marvell>`__).
|
|
|
|
Prerequisites
|
|
-------------

|
Interface Creation and Deletion
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
Interfaces are using new vnet dev APIs, CLIs or startup.conf to create and
|
|
delete interfaces.
|
|
|
|
Sample startup.conf:
|
|
|
|
::
|
|
|
|
devices {
|
|
dev platform/f2000000.ethernet {
|
|
port 1 { name ppio1 }
|
|
}
|
|
|
|
Device identifier in this example is 'platform/f2000000.ethernet' where
|
|
'platform' is bus name and 'f2000000.ethernet' is linux platform bus
|
|
identifier for specific PP2.
|
|
|
|
Platform identifier can be found in sysfs:
|
|
|
|
::
|
|
|
|
$ ls /sys/bus/platform/devices | grep ethernet
|
|
f2000000.ethernet
|
|
