RuleManager hierarchy
=====================
Service net.connman.hwsim
Interface net.connman.hwsim.RuleManager [Experimental]
Object path /
Methods object AddRule()
Create a new blank rule entry. This rule will
match all frames but apply no changes to the frames
until the properties are written some non-default
values. Rules may affect frames being sent over
the wireless medium. Some properties of a rule
determine what frames match it, other properties
determine the effect on matching frames. When
a frame goes through the simulated medium all
matching rules are applied according to their
priority property. See below for specifics on
those properties.
Service net.connman.hwsim
Interface net.connman.hwsim.Rule [Experimental]
Object path /{rule0,rule1,...}
Methods void Remove()
Remove this rule.
Properties string Source
Source device's hardware address in the
XX:XX:XX:XX:XX:XX format or "any". The Source
and Destination addresses refer to the hardware
addresses of the source and the destination
radios as given by the
net.connman.hwsim.Radio.Addresses property
on the radio object (see hwsim-radio-api.txt).
While those addresses initially match the network
interface mac addresses, and that present in the
ethernet headers of each frame, they are
independent.
string Destination
Destination device's hardware address in the
XX:XX:XX:XX:XX:XX format, or one of: "any",
"multicast".
boolean Bidirectional
If false, rule matches frames from Source to
Destination. If true, also matches frames from
Destination to Source.
uint32 Frequency
If non-zero, rule matches specified center
frequency only.
int16 Priority
Rule priority / preference / metric. The rule
will be processed after any rule with a lower
Priority value and may override properties
already modified.
int16 SignalStrength
Signal strength (RSSI) value to set on matching
frames to be seen by the receiver, or zero. If
zero, no change is applied. Signal strength is
expressed in 100 * dBm. The value is in the range
of -1 (strongest signal) to -10000 (weakest
signal).
bool Drop
If true, nothing is passed to the receiver.
uint32 Delay
Set the millisecond delay for any matching packets. This
value cannot be less than 1 as a 1ms delay is required
for test reliability.
