But, as the list of elements of the bond gets built, if a single element is not present, it is still possible for the event to be evaluated. There could be the issue of complete functionality if the wrong element is missing, but that will be handled in the processing of the specific event. > > > + > > + nd_list->netdev = tmp_nd; > > + list_add(&nd_list->node, &lag_work->netdev_list.node);

The event handler for LAG will create a work item to place on the ordered workqueue to be processed. Add in defines for training packets and new recipes to be used by the switching block of the HW for LAG packet steering. Update the ice_lag struct to reflect the new processing methodology.
