c09141e56f net: fix RARP generation
Due to a mistake operation from me, older version (v10) was merged to
master branch. It's the v11 should be applied. However, the master branch
is not rebase-able. Thus, this patch is made, from the diff between v10
and v11.

The diffs are:

- Add check for parameter and tailroom in rte_net_make_rarp_packet
- Allocate mbuf in rte_net_make_rarp_packet

Besides that, a link error is fixed when shared lib is enabled.

Fixes: 45ae05df824c ("net: add a helper for making RARP packet")
Fixes: c3ffdba0e88a ("vhost: use API to make RARP packet")

31db4d38de net: change arp header struct declaration
Changed MAC address type from uint8_t[6] to struct ether_addr and IP
address type from uint8_t[4] to uint32_t to make it consistent with
other DPDK code using MAC and IP addresses. It allows us to use
is_same_ether_addr and ether_addr_copy functions on MAC addresses in ARP header.  Also
removed union from arp_hdr struct to make calls to arp_data items
shorter. Updated test-pmd to match new arp_hdr version.

168dfa6166 app/testpmd: add engine that replies to ARP and ICMP echo requests
Add a new specific packet processing engine in the "testpmd" application that
only replies to ARP requests and to ICMP echo requests.
For this purpose, a new "icmpecho" forwarding mode is provided that can be
dynamically selected with the following testpmd command:

    set fwd icmpecho

before starting the receipt of packets on the selected ports.

Then, the "icmpecho" engine performs the following actions on all received
packets:

- replies to a received ARP request by sending back on the RX port a ARP
  reply with a "sender hardware address" field containing the MAC address
  of the RX port,

- replies to a ICMP echo request by sending back on the RX port a ICMP echo
  reply, swapping the IP source and the IP destination address in the IP
  header,

- otherwise, simply drops the received packet.

When replying to a received packet that was encapsulated into a VLAN tunnel,
the reply is sent back with the same VLAN identifier.
By default, the testpmd configures VLAN header stripping RX option on each
port.
This option is not managed by the icmpecho engine which won't detect
packets that were encapsulated into a VLAN.
To address this issue, the VLAN header stripping option must be previously
switched off with the following testpmd command:

    vlan set strip off

When the "verbose" mode has been set with the testpmd command
"set verbose 1", the "icmpecho" engine displays informations about each
received packet.

The "icmpecho" forwarding engine can also be used to simply check port
connectivity at the hardware level (check that cables are well-plugged)
and at the software level (receipt of VLAN packets, for instance).
