The format is as follows: device_declaration := [,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.
