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.
