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 - 27: updating member port activation handler

Updating the #member #port #activation handler in LAG module. The references to the augmented custom member port data-structures has been updated to the standard member port data-structures. This allows to directly use the #standard #member #port data-structure and use the #embedded custom member port data-structure for internal operations. The #status related parameters are kept in the custom data-structure and on member port status #change these are updated as #active / #not-in-service. When ports are not ready to participate in the normal operations because of inconsistency in the applied configuration the state is set as #not-ready.

LAG upgrade - 26: cleaning up LAG management framework for data-structure changes

Added miscellaneous changes in #management #framework in LAG module. #Cleaned up #aggregator #activation handler and added #initialized aggregator #parameters with their #default values. Corrected standard #extended #member #port #iterator routine to provide reference to the standard member port, so that extended parameters embedded in them can be accessed in the mapper routine. Corrected #member #port #create #API to create #statistics, #debug and #extended port #data-structures as part of the member port creation. Corrected #aggregator #create #API to create the #member port #list as part of aggregator creation.

LAG upgrade - 24: removing custom member port create API

Removed #custom #member #port #create / #remove API in LAG module. The custom member port entries are #embedded in the #standard #member #port entries and the standard member port create / remove API already handles the required functionality. Hence the redundant external API is being removed.

Hard-linked #member #port #list #configuration in LAG module. The member port list has been #embedded in the #standard #aggregator configuration #entries. This removes the redundant indexing scheme and optimizes the memory used by the member port list entries. The member port list is a #single #entry corresponding to each #aggregator #port, it contains a #bit-map of member port #interface-indexes. For #scalability reasons this data-structure is #not #used any more and the #custom #member #port list is used which can be used in all cases.

Updated #external #create / #remove #API for #member #ports in LAG module. Removed references to augmented data-structures from these routines. The external #create API creates the member port configuration entry and it's #associated #data-structures like port #statistics and #debugging parameters. The #custom member port parameter entries and #extended configuration entries are also #instantiated along with the create operation.

LAG logical port update - 2

Added changes in lag module for handling the #lag #aggregator #logical #interface #status #change s. Similar status handler has been added for #lag #member #port s as well. When member port status is changed in other modules (e.g. ethernet) it will cascaded to lag module. The member port status changes may cause aggregator port status change as well. This will enable lag module to perform aggregator specific operations to be performed on relation with the member port status change.
