Dumping the packet type is useful for debug purposes. Instead
of having each application providing its function to do that,
introduce functions to do it.
It factorizes the code and reduces the risk of desynchronization between
the new packet types and the dump function.

Introduce the function rte_net_get_ptype() that parses a mbuf and
returns its packet type. For now, the following packet types are parsed:
L2: Ether
L3: IPv4, IPv6
L4: TCP, UDP, SCTP
The goal here is to provide a reference implementation for packet type
parsing. This function will be used by testpmd in next commits, allowing
to compare its result with the value given by the hardware.
This function will also be useful when implementing Rx offload support
in virtio pmd. Indeed, the virtio protocol gives the csum start and
offset, but it does not give the L4 protocol nor it tells if the
checksum is relevant for inner or outer. This information has to be
known to properly set the ol_flags in mbuf.

Introduce a new function to read the packet data from an mbuf chain. It
linearizes the data if required, and also ensures that the mbuf is large
enough.
This function is used in next commits that add a software parser to
retrieve the packet type.

NIST SP800-38A recommends two methods to generate unpredictable IVs
(Initilisation Vector) for CBC mode:
1) Apply the forward function to a nonce (ie. counter)
2) Use a FIPS-approved random number generator
This patch implements the first recommended method by using the forward
function to generate the IV.

This patch adds the configuration file support to ipsec_secgw
sample application. Instead of hard-coded rules, the users can
specify their own SP, SA, and routing rules in the configuration
file. A command line option "-f" is added to pass the
configuration file location to the application.
Configuration item formats:
SP rule format:
sp <ip_ver> <dir> esp <action> <priority> <src_ip> <dst_ip> \
<proto> <sport> <dport>
SA rule format:
sa <dir> <spi> <cipher_algo> <cipher_key> <auth_algo> <auth_key> \

This feature adds vhost pmd extended statistics from per port perspective
in order to meet the requirements of the applications such as OVS etc.
RX/TX xstats count the bytes without CRC. This is different from physical
NIC stats with CRC.
The statistics counters are based on RFC 2819 and RFC 2863 as follows:
rx/tx_good_packets
rx/tx_total_bytes
rx/tx_missed_pkts
rx/tx_broadcast_packets
rx/tx_multicast_packets
rx/tx_unicast_packets
rx/tx_undersize_errors
rx/tx_size_64_packets
rx/tx_size_65_to_127_packets;
rx/tx_size_128_to_255_packets;
rx/tx_size_256_to_511_packets;
rx/tx_size_512_to_1023_packets;
rx/tx_size_1024_to_1522_packets;
rx/tx_1523_to_max_packets;
rx/tx_errors
rx_fragmented_errors
rx_jabber_errors
rx_unknown_protos_packets;
No API is changed or added.
rte_eth_xstats_get_names() to retrieve what kinds of vhost xstats are
supported,
rte_eth_xstats_get() to retrieve vhost extended statistics,
rte_eth_xstats_reset() to reset vhost extended statistics.
The usage of vhost pmd xstats is the same as virtio pmd xstats.
for example, when test-pmd application is running in interactive mode
vhost pmd xstats will support the two following commands:
show port xstats all | port_id will show vhost xstats
clear port xstats all | port_id will reset vhost xstats
net/virtio pmd xstats(the function virtio_update_packet_stats) is used
as reference when implementing the feature.

Indirect descriptors are usually supported by virtio-net devices,
allowing to dispatch a larger number of requests.
When the virtio device sends a packet using indirect descriptors,
only one slot is used in the ring, even for large packets.
The main effect is to improve the 0% packet loss benchmark.
A PVP benchmark using Moongen (64 bytes) on the TE, and testpmd
(fwd io for host, macswap for VM) on DUT shows a +50% gain for
zero loss.
On the downside, micro-benchmark using testpmd txonly in VM and
rxonly on host shows a loss between 1 and 4%. But depending on
the needs, feature can be disabled at VM boot time by passing
indirect_desc=off argument to vhost-user device in Qemu.

As discussed in the past release, driver names are modified
to be more consistent, and the future driver should follow
this new convention.
Driver names consist of:
"driver category"_"driver folder name"_"optional extra name".
For example:
- Crypto null driver -> "crypto_null"
- Network IXGBE VF driver -> "net_ixgbe_vf"

Following discussions on the mailing list [1] and since nobody stood up to
implement the necessary cleanups, here is the ivshmem integration removal.
There is not much to say about this patch, a lot of code is being removed.
The default configuration file for packet_ordering example is replaced with
the "native" x86 file.
The only tricky part is in eal_memory with the memseg index stuff.
More cleanups can be done after this but will come in subsequent patchsets.
