Subject: [PATCH] examples/l2fwd_acl: add ACL-based L2 forwarding example

This example demonstrates usage of the DPDK ACL library
to classify packets based on:

- protocol
- source IPv4
- destination IPv4
- source port
- destination port

Packets matching ACL rules are forwarded,
others are dropped.

The example provides a minimal reference
for developers wanting to integrate ACL
classification into packet forwarding paths.
