The techboard decision is a bit different of this l3fwd-regex:
"
- TB agreed to have an example application that exercises the regex device and network device as a separate application.
- The example shall be used for both Benchmark and functional verification of regex in the forwarding path.
- Based on the discussions, it is agreed that l3fwd might not be the real use case to consider as regex + network application
- Instead, TB recommends having the Deep packet inspection style application to showcase the regex + networking use case.
- Following is the simple DPI style application definition, which can be considered as a candidate, as an example of regex + network application
1) Create or import a rule database.
        - Rule database will have an index as rule_id and pattern to search
2) Create or import rule_id to the action table
              - Action could be -1 for the drop, 0 .. N for a specific port to forward upon the match
3) Enqueue all the packet from ethdev to regexdev
4) If there is a match, then do the action based on the table created in step 2 using struct rte_regexdev_match::rule_id
5) If there is no match, forward back to the source port
