LACP upgrade - 10: updating LACP PDU partner info handler

Updated the LACP #PDU #handler in #LACP module. This handler will #process the #PDU while #received on port. The #peer #partner #info of the received port is #updated from the info received in the LACP PDU. The info in the PDU is checked against the actor port specific info to #decide whether the #peer port is in #sync with the received port. The partner info like oper-port, oper-priority, oper-system-id, oper-system-priority, oper-key and oper-stat are populated according to the values received from LDU. The actor specific info like port, port-priority, system-id, system-priority and oper-key are cross checked with the info in PDU to decide whether synchronization has been attained with the peer port.

LACP upgrade - 9: updating LACP PDU transmit handler

Updated the #PDU #transmit #handler in the #LACP module. Whenever updated LACP packets has to be sent to the #peer #partner node, the PDUs are #composed from the internal data-structures in this routine. This routine access the member port data-structures for #creating the individual #TLVs in the LACP PDU. The data-structure references has been corrected to the native member port structures. This routine passes the created PDUs to the appropriate #platform #handlers to send them out of the actual port.

LACP upgrade - 8: updating the LACP PDU processing routine

Updated the internal #LACP #PDU #processing routine in LACP module. This handler #disects the LACP #packet in to individual #TLVs and do the respective handling. The LACP PDU receive handler passes the incoming PDUs to this routine for processing. The routine has been upgraded to use the native member port level data-structures for it's internal processing.

LACP upgrade - 7: updating the received LACP PDU handler

Updated incoming #LACP #PDU #handler in LACP module. The PDU handler has been updated to use native member port structures. The #peer #partner #data-structures on the particular member port are updated and internal LACP state on the port is updated in the handler. The routine to update the peer partner data-structures with the #administratively configured #default #values has been updated to remove references to the augmented data-structures. The #partner #info #expire #handler also has been updated in the same lines.

LACP upgrade - 6: updating member port aggregator attach handler

Updated #member #port #attach #handler with the aggregator in the #LACP module. This handler make the #hardware calls to #attach the member port with the selected aggregator and mark the member port state as attached. The #remote #peer is informed of this by sending a #new #LACP #PDU and peer is marked as #synchronized. Later, when peer responds with it's PDU the actual #distribution and #collection operations will be #started for member ports. On attaching the member port with the aggregator the LAG distribution and collection operations will be started in hardware. i.e. The traffic sent out on the aggregator port will be distributed to the member ports and traffic received on the member ports will be collected on to the combined aggregator port.

LAG upgrade - 19: updating standard extended member port agent mapper routines

Updated #standard #extended #member #port agent routines in LAG module. The agent #iterator routines and #mapper #routine has been updated to use standard #member #port #based #indexing. This will access the extended member port entries #embedded in the standard #member #port entries and there by removing the redundant indexing. The standard extended member port entries contain #attributes like the #custom #destination #address for the #LACP control and marker #PDUs.

LAG upgrade - 16: optimizing standard extended LAG member port entries

Updated #standard #extended #member #port agent mapper routines in LAG module. The agent #iterator routines and #mapper #routine has been updated to use standard member port entry based #indexing. This will access the port entries by using the #native #indexing. This removes references to the standard member port statistics indexing used earlier. The extended entries add support for #attributes like #custom #destination #address for the #LACP control and marker #PDUs, these will #default to the standard #Slow_Protocols_Multicast address.

LACP PDU processing update - 1: link LACP PDU processing routine with module message queue

Added changes in LACP module to connect the #message #queue with #PDU #processing routine. This will extract the LACP PDUs added in the message queue and send them to PDU processing routine. This will perform the #aggregator and #member #port related operations based on the #received #LACP #PDU s.

LACP update - 9: LACP incoming PDU receive

Created a #message #queue in LACP module for #handling #LACP #PDU s. This will enable #HAL module to #trap the #LACP #PDU s from #ports and pass them over to #LACP module as messages for processing. The message library APIs for sending and receiving the messages are used for this purpose. The thread APIs are used to create a #waiting #message #loop in LACP module.
