lacp: partner may time us out if fast-rate is configured [VPP-1247]
We should be sending LACP PDU every second if the partner has LACP_TIMEOUT flag set which means it will time us out in 3 seconds. Add interface name for lacp trace Change-Id: If7d816c062d03e80cc0dd7d10dba0b76ace0664a Signed-off-by: Steven <sluong@cisco.com>
