DrainState IGbE::drain ( )
overridevirtual

Notify an object that it needs to drain its state.

If the object does not need further simulation to drain internal buffers, it returns DrainState::Drained and automatically switches to the Drained state. If the object needs more simulation, it returns DrainState::Draining and automatically enters the Draining state. Other return values are invalid.

Note
An object that has entered the Drained state can be disturbed by other objects in the system and consequently stop being drained. These perturbations are not visible in the drain state. The simulator therefore repeats the draining process until all objects return DrainState::Drained on the first call to drain().
Returns
DrainState::Drained if the object is drained at this point in time, DrainState::Draining if it needs further simulation.

Implements Drainable.

Tick IGbE::writeConfig ( PacketPtr  pkt)
overridevirtual

Write to the PCI config space data that is stored locally.

This may be overridden by the device but at some point it will eventually call this for normal operations that it does not need to override.

Parameters
pktpacket containing the write the offset into config space

Reimplemented from PciDevice.
