Hi Praveen,

I do have some review comments on the code. Before that, can you give a brief overview of what is being targeted? My understanding is that the primary objective is to use rte_flow (or flow director) to redirect a specific flow(/SA) to a specific queue. Can you confirm?

Couple of questions,
1. I would assume the new option of "flow-direction" is optional and is determined per SA. In that case, can I assume that RSS would be active for the other flows (or SAs). Let's say, I just want to add a SA for which I would like to enable "flow-direction" but leave the rest as is. How is that handled?
2. I see that the changes are only applicable for LOOKASIDE_PROTOCOL. The same feature would be useful for other modes as well, right?
3. I'm not sure "flow-direction" is the right wording for the option. This is just specifying the "rx-queue" per SA. @Akhil, Konstantin, comments?

Thanks,
Anoob

Hi Anoob,

Thank you.

Please see my answers below.

Hi Praveen,

I do have some review comments on the code. Before that, can you give a brief overview of what is being targeted? My understanding is that the primary objective is to use rte_flow (or flow director) to redirect a specific flow(/SA) to a specific queue. Can you confirm?

Couple of questions,
1. I would assume the new option of "flow-direction" is optional and is determined per SA. In that case, can I assume that RSS would be active for the other flows (or SAs). Let's say, I just want to add a SA for which I would like to enable "flow-direction" but leave the rest as is. How is that handled?

[Praveen]

>>>> We are using fdir_flag to differentiate the mix of SA's(SA's with and without flow-direction).
>>>> fdir_flag will be "set" for the SA which has configured with flow-direction option(SA rule syntax is extended to 	add new options  <action_type>  <portid>  <queueid> ).
>>>> flow creation is called only for the SA's with fdir_flag is set.

2. I see that the changes are only applicable for LOOKASIDE_PROTOCOL. The same feature would be useful for other modes as well, right?

[Praveen]
>>>>  We are adding this feature for i40e NIC and the  i40e NIC doesn't support either encryption or decryption, that's why we used only LOOKASIDE_PROTOCOL in this case.

3. I'm not sure "flow-direction" is the right wording for the option. This is just specifying the "rx-queue" per SA. @Akhil, Konstantin, comments?

 >>>> @Declan, @Konstantin ,  @Bernard, @Akhil  Could you please suggest a name on which we can all agree  upon?

Thanks,
Anoob

[Anoob] May be update the commit description with some more such details. And I think it's better to use 'rte_flow' rather than flow director. I see that i40e PMD talks about flow director, but overall the feature is usage of rte_flow.

[Anoob] I've few questions on this. I'll send this along with my code review.

[Anoob] I meant LOOKASIDE_NONE (LOOKASIDE_CRYPTO) case. I would assume that can be early supported.

[Anoob] May be update the commit description with some more such details. And I think it's better to use 'rte_flow' rather than flow director. I see that i40e PMD talks about flow director, but overall the feature is usage of rte_flow.
 
[Praveen]  Yeah Sure , I will add more such details in v2.

[Anoob] I've few questions on this. I'll send this along with my code review.

[Anoob] I meant LOOKASIDE_NONE (LOOKASIDE_CRYPTO) case. I would assume that can be early supported.

[Praveen]  Yes , it was a copy & paste error , what I meant was LOOKASIDE_NONE. Will fix this in v2.
