ethdev: update link status after start
Since LSR interrupt is disabled by pmd drivers, link status in rte_eth_device is always down.
Bond slave_configure() enables LSR interrupt on devices to get notification if link status
changes. However, the LSC interrupt at device start time is still lost.
In this fix, call link_update to read link status from hardware
register at device start time.

examples/packet_ordering: new sample app
This new app makes use of the librte_reorder library.
It requires at least 3 lcores for RX, Workers (1 or more) and TX threads.
Communication between RX-Workers and Workers-TX is done by using rings.
The flow of mbufs is the following:
* RX thread gets mbufs from driver, set sequence number and enqueue
them in ring.
* Workers dequeue mbufs from ring, do some 'work' and enqueue mbufs in
ring.
* TX dequeue mbufs from ring, inserts them in reorder buffer, drains
mbufs from reorder and sends them to the driver.

i40e: remove the use of UDP tunnel flag
The definition of the flag PKT_TX_UDP_TUNNEL_PKT in rte_mbuf.h was:
TX packet is an UDP tunneled packet. It must be specified when using
outer checksum offload (PKT_TX_OUTER_IP_CKSUM)
This flag was used to tell the NIC that the offload type is UDP
(I40E_TXD_CTX_UDP_TUNNELING flag). In the datasheet, it says it's
required to specify the tunnel type in the register. However, some tests
(see [1]) showed that it also works without this flag.
Moreover, it is not explained how the hardware use this
information. From a network perspective, this information is useless for
calculating the outer IP checksum as it does not depend on the payload.
Having this flag in the API would force the application to specify the
tunnel type for something that looks only useful for this PMD. It will
limit the number of possible tunnel types (we would need a flag for each
tunnel type) and therefore prevent to support outer IP checksum for
proprietary tunnels.
Finally, if a hardware advertises "I support outer IP checksum", it must
be supported for any payload types.
This has been validated by [2], knowing that the ipip test case was fixed
after this test report [3].

From i40e datasheet:
The IP header type and its offload. In case of tunneling, the IIPT

00 - non IP packet or packet type is not defined by software
01 - IPv6 packet
10 - IPv4 packet with no IP checksum offload
11 - IPv4 packet with IP checksum offload
Therefore it is not needed to fill the IIPT field if no offload is
requested (we can keep the value to 00). For instance, the linux driver
code does not set it when (skb->ip_summed != CHECKSUM_PARTIAL). We can
do the same in the dpdk driver.

Testpmd has the capability of changing the forwarding cores and ports in runtime.
If these are changed when forwarding, two issues may be encountered:
- If "show config fwd" is used, changes made in the core list are applied.
Therefore, trying to stop forwarding may hang testpmd,
since it could be waiting for cores to stop that are not actually running anything
- If the port list is changed, when stopping forwarding,
it may miss the stats of some of the ports that were actually being used.
