void Evl_BridgeInsertPktInIbuf	(	Evl_Bridge_t *	aBridge,
		Pkt_EthernetHdr_t *	aPkt
	)

Insert a packet into the bridge iBuf, meant to support scripts/code adding control/reset packets.

Definition at line 1472 of file evlMain.c.

bool Evl_DoAction	(	Evl_Action_t *	action,
		Evl_Manager_t *	mgr,
		Evl_Bridge_t *	bridge,
		Pkt_ProcessPkt_t *	pp
	)
