EthPassthru

typedef struct EthPassthru EthPassthru

Ethernet pass-through face and its associated TAP port.

This struct also serves as the RxGroup of the TAP port.

Function Documentation

EthPassthru_FaceRxInput()

void EthPassthru_FaceRxInput	(	Face *	face,
		int	rxThread,
		FaceRxInputCtx *	ctx
	)

Process a burst of received Ethernet frames on a pass-through face.

This is set as Face_RxInputFunc of a pass-through face. It transmits every packet out of the associated TAP ethdev.

EthPassthru_TapPortRxBurst()

void EthPassthru_TapPortRxBurst	(	RxGroup *	rxg,
		RxGroupBurstCtx *	ctx
	)

Receive Ethernet frames on a TAP ethdev associated with a pass-through face.

This is set as RxGroup_RxBurstFunc of a TAP ethdev associated with a pass-through face. It enqueues every packet into the output queue of the pass-through face.

EthPassthru_TxLoop()

uint16_t EthPassthru_TxLoop	(	Face *	face,
		int	txThread
	)

Process outgoing Ethernet frames on a pass-through face.

This is set as Face_TxLoopFunc of a pass-through face. It transmits every packet out of the (physical) DPDK ethdev.
