This comment is true (and it appears it is always on in 802.3ad mode):
/* use this port as agregator */
port->aggregator_port_id = slave_id;
rte_eth_promiscuous_enable(slave_id);
If we are going to do this here, we should probably get rid of it in
the other location so that future readers aren't confused about which
is the one doing the work.
Since some adapters don't have group multicast support, we might
already be in promiscuous anyway. Turning off promiscuous for
the bonding master might turn it off in the slaves where an application
has already enabled it.
