Add a new generic device declaration parameter:
--dev=<device_declaration>
That allows to declare device from any bus. The format is as follows:
device_declaration := <bus><c><device>[,arg_list]
bus := bus name
c := arbitrary character separator
device := device name (PCI location, virtual PMD name, ...)
arg_list := key value list: key1=val1[,key2=val2[,...]]
The bus name is mandatory. The character separator can be anything.
The device name is mandatory. The argument list is optional.
Examples:
--dev=pci:0000:05:00.0,port=1
--dev=vdev_net_ring0
