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.

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.
