I have observed that the member links are participating and are part of the active aggregator while the traffic is egressing via only one member link (in a case where two links are participating). Via kprobes I discovered that slave-arr has only one link added while the other participating link wasn't part of the slave-arr. I couldn't see what caused that situation but the simple code-walk through provided me hints that the enable_port wasn't always associated with the slave-array update.
