  l3fwd-acl contains duplicate functions to l3fwd.
For this reason we merge l3fwd-acl code into l3fwd
with '--lookup acl' cmdline option to run ACL.

Patch also needs to remove/update the docs for:
https://doc.dpdk.org/guides-21.11/sample_app_ug/l3_forward_access_ctrl.html
https://doc.dpdk.org/guides-21.11/sample_app_ug/l3_forward.html

LGTM in general, some comments, mostly nits inline.
As one generic comment - doc update seems missing. 
Thanks

I don't think we do need these define any more.
Probably we can safely remove it.

Probably just:
extern struct acl_algorithms acl_alg[];

Do we really need all these includes?
Probably some of them could be safely removed?

As I can see acl parse_ptype functions are identical to em conterparts.
If so then we probably can remove dups and use the same functions for both cases.

Same here, seems identical to em_check_ptype().
If so, can we possibly re-use existing one?

Probably no point to have print routines as 'static online'.
They do not belong to fast-path.

Is that a dup of send_single_packet() fro l3fwd.h?
If so, then better to use the original one and remove that one as a duplicate.

I don't see where we update mac addresses for outgoing packets...
Is that part missing in updated acl code-path?
If so, then we probably need to put it back.
In fact, I wonder can we apply the same code as is done for fib:
- in l3fwd_acl_prepare_one_packet() remove all  packet modifications and
   ipv4 validity checks. So it will become something really simple like that: 
   
static inline void
l3fwd_acl_prepare_one_packet(struct rte_mbuf **pkts_in, struct acl_search_t *acl,
	int index)
{
	struct rte_mbuf *pkt = pkts_in[index];

	if (RTE_ETH_IS_IPV4_HDR(pkt->packet_type)) {
		/* Fill acl structure */
		acl->data_ipv4[acl->num_ipv4] = MBUF_IPV4_2PROTO(pkt);
	} else if (RTE_ETH_IS_IPV6_HDR(pkt->packet_type)) {
		/* Fill acl structure */
		acl->data_ipv6[acl->num_ipv6] = MBUF_IPV6_2PROTO(pkt);
	} else {
		/* Unknown type, drop the packet */
		rte_pktmbuf_free(pkt);
	}
}

- in l3fwd_acl_send_packets() do what fib (and other ) code paths do:

#if defined SEND_MULTI
        send_packets_multi(...);
#else
        l3fwd_acl_send_packets(...);
#endif
