User can't directly control number of tries per context and/or contents of each trie at build time.
It is decided by build time by librte_acl internal logic and depends from the rule set and build parameters.
Please refer to: http://dpdk.org/doc/guides/prog_guide/packet_classif_access_ctrl.html
Section 23.1.2. RT memory size limit.
> 3. If we can create ACL context using multiple tries, then is it possible to have trie per category in ACL context?

No, that's no possible with current implementation.
