Hi,
Is there a way in DPDK to configure Mellanox ConnectX-5 Ex to distribute
the incoming packets of a single flow type to multiple NIC hardware queues?
Does ConnectX-5 Ex PMD support constantly changing the RETA table during
runtime without having to stop and start the device for the table to get
updated and for the packets to get dispatched to multiple cores? Could this
be a possible solution?
Thanks
Anna

Yes, use rte_flow and rte_flow_action_type_rss.

The Reta table is only used without rte_flow.
Use rte_flow it is a better solution.
