I'm fine with any approach, but we need to > consider making at-least l3fwd & ipsec-secgw also event driven. > With this approach, following may be the challenges: 1. Documentation will be required for user to use eventdev helper library. 2. Helper library should cater all the generic use cases which can be catered from rte_eventdev_*** library. If not, supported configuration/use cases should also be documented and should be future evolving with eventdev library enhancements. > Thanks, > Anoob
