We already had /if/lacp/<bond-sw_if_index>/<slave-sw_if_index>/state in the stats segment. Add also the partner-state to be complete. Change to populate stats segment with the states at startup, after processing an lacp pdu, and after timer expiration. Unit test --------- sudo vpp_get_stats dump | grep /if/lacp 63.00 /if/lacp/3/1/state 61.00 /if/lacp/3/1/partner-state 63.00 /if/lacp/3/2/state 61.00 /if/lacp/3/2/partner-state Type: feature Signed-off-by: Steven Luong <sluong@cisco.com> Change-Id: Ib7b8e1183d572bb6e422a846aaa2b7b3559a0dc7
