[dpdk-dev] ACL trie insertion and search

[Rapelly, Varun]

Hi,

We were converting the acl rule data, from host to network byte order, [by mistake] while inserting into trie. And while searching we are not converting the search data to n/w byte order.
With the above also rules are matching, except few scenarios.

After correcting the above mistake, all rules are matching perfectly fine.

I believe the above[converting while insertion] should also work for all rules. Please clarify the above.

Regards,
Varun

Yes, that's correct.
rte_acl_add_rules() expects all fields to be in host byte order, while
rte_acl_classify()expects all fields in input data buffers to be in network byte order.
As mentioned in comments in rte_acl.h.
