Questions about rte_eth_dev multiple rx queue selection (~/dpdk/lib/librte_ether).

[최익성]

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.

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

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.

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

 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.

[Zhang, Helin]

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.
