Hi Mr. Choi,
Please refer to testpmd, we demonstrate filtering to a selected queue.
There are plenty of functions that allow you to select a queue:-
Exp:-
Add or delete a L2 Ethertype filter, which identify packets by their L2 Ethertype mainly assign
them to a receive queue.
ethertype_filter (port_id) (add|del) (mac_addr|mac_ignr) (mac_address) ethertype
(ether_type) (drop|fwd) queue (queue_id)
The available information parameters are:
• port_id: the port which the Ethertype filter assigned on.
• mac_addr: compare destination mac address.
• mac_ignr: ignore destination mac address match.
• mac_address: destination mac address to match.
• ether_type: the EtherType value want to match, for example 0x0806 for ARP packet.
0x0800 (IPv4) and 0x86DD (IPv6) are invalid.
• queue_id : The receive queue associated with this EtherType filter. It is meaningless
when deleting or dropping.
There are 2tuple,5tuple,syn, flex filters and flow director
Regards,
Choi, Sy Jong

Subject: [dpdk-dev] Questions about rte_eth_dev multiple rx queue selection (~/dpdk/lib/librte_ether).
Dear DPDK experts.
I really appreciate for your precious answers and advices and thank you for your great contributions.
I have questions about rte_eth_dev multiple rx queue usage (~/dpdk/lib/librte_ether).
Please let me know, if I am wrong or I have something missed.
The applications use rte_eth_dev_configure( port, n_rx_queues, n_tx_queues, &port_conf) to setup multiple rx queues for a port.
How can we select rx queues for the packets from a port? Is there any rx queue selection function?
Is it determined by NIC and is the rx queue information delivered to DPDK?
I will appreciate to you if I can be given any answer, advice, and comments.
Thank you very much.
Sincerely Yours,
Ick-Sung Choi.

Dear Zhang, Helin.
Thank you very much for your advice and answer.
I guess RSS queue selection is performed in NIC.
Would you tell me more about redirection table? Where can I find reference for it?
Thank you very much.
Sincerely Yours,
Ick-Sung Choi.

You can refer to 'RSS' and 'redirection table' first.

RSS and redirection table is popular features in almost all NICs, so you can refer to NIC datasheet or google.
It is easy to find out good articles.
