Message-ID: <DB8PR04MB66356B62044FC2A29E910621E6C90@DB8PR04MB6635.eurprd04.prod.outlook.com> (raw)

Hi Praveen,
Sorry for being late to reply on this, Please delegate the patches properly from next time in patchworks.
This patch was neither delegated to me, nor I was in to/cc. So it got missed.

Please add documentation (doc/guides/sample_app_ug/ipsec_secgw.rst) changes
to explain the new parameter.

Fdir_conf is a deprecated parameter. It is not good to introduce
Something new in the application with a deprecated parameter.
Please use the recommended way to configure flows.

It means it is supported in cpu crypto as well? Better to have a check for the supported
Action types, as in the future there may be some other action types.
