What I meant was, if there are multiple MAC addresses on a port, the bcast/mcast
flows will be repeated. For example, if there are 3 valid addrs in
dev->data->mac_addrs

    testpmd> mac_addr add 0 <addr1>
    testpmd> mac_addr add 0 <addr2>
    testpmd> mac_addr add 0 <addr3>

and 2 vlan filters are configured like your example above, then 6 ucast flows
(2 per an addr) will be added along with 6 bcast flows and 6 mcast flows. But it
only needs 2 bcast flows and 2 mcast flows - one per vlan.
