Functions
void	pTcpLsn (stream< TcpAppLsnReq > &soTOE_LsnReq, stream< TcpAppLsnRep > &siTOE_LsnRep, stream< TcpPort > &sTcpPortsToOpen, stream< bool > &sTcpPortsOpenFeedback)
	Request the TOE to start listening (LSn) for incoming connections on a specific port (.i.e open connection for reception mode). More...
void	pTcpRxNotifEnq (ap_uint< 1 > *layer_4_enabled, ap_uint< 1 > *piNTS_ready, stream< TcpAppNotif > &siTOE_Notif, stream< TcpAppNotif > &sTcpNotif_buffer)
	Enqueus the incoming notificiations from TOE into the internal buffer. More...
void	pTcpRRh (ap_uint< 1 > *layer_4_enabled, ap_uint< 1 > *piNTS_ready, ap_uint< 32 > *piMMIO_CfrmIp4Addr, ap_uint< 16 > *piMMIO_FmcLsnPort, stream< TcpAppNotif > &siTOE_Notif, stream< TcpAppRdReq > &soTOE_DReq, stream< NalNewTableEntry > &sAddNewTriple_TcpRrh, stream< SessionId > &sMarkAsPriv, stream< SessionId > &sDeleteEntryBySid, stream< TcpAppRdReq > &sRDp_ReqNotif, stream< PacketLen > &fmc_write_cnt_sig, stream< PacketLen > &role_write_cnt_sig)
	ReadRequestHandler (RRh). Waits for a notification indicating the availability of new data for the ROLE or FMC. More...
void	pTcpRDp (ap_uint< 1 > *layer_4_enabled, ap_uint< 1 > *piNTS_ready, stream< TcpAppRdReq > &sRDp_ReqNotif, stream< TcpAppData > &siTOE_Data, stream< TcpAppMeta > &siTOE_SessId, stream< NetworkWord > &soFMC_data, stream< TcpSessId > &soFMC_SessId, stream< NetworkWord > &soTcp_data, stream< NetworkMetaStream > &soTcp_meta, stream< NalConfigUpdate > &sConfigUpdate, stream< Ip4Addr > &sGetNidReq_TcpRx, stream< NodeId > &sGetNidRep_TcpRx, stream< SessionId > &sGetTripleFromSid_Req, stream< NalTriple > &sGetTripleFromSid_Rep, ap_uint< 32 > *piMMIO_CfrmIp4Addr, ap_uint< 16 > *piMMIO_FmcLsnPort, ap_uint< 1 > *layer_7_enabled, ap_uint< 1 > *role_decoupled, stream< bool > &cache_inval_sig, stream< NalEventNotif > &internal_event_fifo)
	Read Path (RDp) - From TOE to ROLE or FMC. Process waits for a new data segment to read and forwards it to ROLE or FMC. Invalid packets are dropped. More...
void	pRoleTcpRxDeq (ap_uint< 1 > *layer_7_enabled, ap_uint< 1 > *role_decoupled, stream< NetworkWord > &sRoleTcpDataRx_buffer, stream< NetworkMetaStream > &sRoleTcpMetaRx_buffer, stream< NetworkWord > &soTcp_data, stream< NetworkMetaStream > &soTcp_meta, stream< PacketLen > &role_write_cnt_sig)
	Terminates the internal TCP RX FIFOs and forwards packets to the Role. More...
void	pFmcTcpRxDeq (stream< NetworkWord > &sFmcTcpDataRx_buffer, stream< TcpSessId > &sFmcTcpMetaRx_buffer, stream< NetworkWord > &soFmc_data, stream< TcpSessId > &soFmc_meta, stream< PacketLen > &fmc_write_cnt_sig)
	Terminates the internal TCP RX FIFOs and forwards packets to the FMC. More...
void	pTcpWRp (ap_uint< 1 > *layer_4_enabled, ap_uint< 1 > *piNTS_ready, stream< NetworkWord > &siFMC_data, stream< TcpSessId > &siFMC_SessId, stream< NetworkWord > &siTcp_data, stream< NetworkMetaStream > &siTcp_meta, stream< TcpAppData > &soTOE_Data, stream< TcpAppMeta > &soTOE_SessId, stream< TcpDatLen > &soTOE_len, stream< NodeId > &sGetIpReq_TcpTx, stream< Ip4Addr > &sGetIpRep_TcpTx, stream< NalTriple > &sGetSidFromTriple_Req, stream< SessionId > &sGetSidFromTriple_Rep, stream< NalTriple > &sNewTcpCon_Req, stream< NalNewTcpConRep > &sNewTcpCon_Rep, stream< bool > &cache_inval_sig, stream< NalEventNotif > &internal_event_fifo)
	Write Path (WRp) - From ROLE or FMC to TOE. Process waits for a new data segment to write and forwards it to TOE. More...
void	pTcpWBu (ap_uint< 1 > *layer_4_enabled, ap_uint< 1 > *piNTS_ready, stream< TcpAppData > &siWrp_Data, stream< TcpAppMeta > &siWrp_SessId, stream< TcpDatLen > &siWrp_len, stream< TcpAppData > &soTOE_Data, stream< TcpAppSndReq > &soTOE_SndReq, stream< TcpAppSndRep > &siTOE_SndRep)
	Write Buffer (WBu) - From WRp to TOE. Process to synchronize with TOE's TX buffer (and it's available space). In case of streaming mode (i.e. ROLE's length was 0), WRp takes care of splitting the data and writing the right len. More...
void	pTcpCOn (stream< TcpAppOpnReq > &soTOE_OpnReq, stream< TcpAppOpnRep > &siTOE_OpnRep, stream< NalNewTableEntry > &sAddNewTriple_TcpCon, stream< NalTriple > &sNewTcpCon_Req, stream< NalNewTcpConRep > &sNewTcpCon_Rep)
	Client connection to remote HOST or FPGA socket (COn). More...
void	pTcpCls (stream< TcpAppClsReq > &soTOE_ClsReq, stream< bool > &sGetNextDelRow_Req, stream< SessionId > &sGetNextDelRow_Rep, stream< bool > &sStartTclCls)
	Asks the TOE to close Tcp connections, based on the request from pPortLogic. More...
