It seems that RTE_MBUF_SCATTER_GATHER is not the proper name for the
feature it provides. "Scatter gather" means that data is stored using
several buffers. RTE_MBUF_REFCNT seems to be a better name for that
feature as it provides a reference counter for mbufs.
The macro RTE_MBUF_SCATTER_GATHER is poisoned to ensure this
modification is seen by drivers or applications using it.

The Packet Framework pipeline library provides a standard methodology
(logically similar to OpenFlow) for rapid development of complex packet
processing pipelines out of ports, tables and actions.
A pipeline is constructed by connecting its input ports to its output ports
through a chain of lookup tables. As result of lookup operation into the
current table, one of the table entries (or the default table entry, in case
of lookup miss) is identified to provide the actions to be executed on the
current packet and the associated action meta-data.
The behavior of user actions is defined through the configurable table action
handler, while the reserved actions define the next hop for the current packet
(either another table, an output port or packet drop) and are handled
transparently by the framework.

Various types of hash tables presented under the Packet Framework toolbox.
Hash table types:
1. Extendible bucket (ext): when bucket is full, bucket is extended with
more keys
2. Least Recently Used (LRU): when bucket is full, the LRU entry is discarded
3. Pre-computed key signature: RX core extracts the key n-tuple from the
packet, computes the key signature and saves the key and key signature
within the packet meta-data; flow classification core performs the actual
lookup (the bucket search stage) after reading the key and key signature
from packet meta-data
4. Signature computed on-the-fly (do-sig version): the same CPU core extracts
the key n-tuple from pkt, computes key signature and performs the table
lookup
5. Configurable key size or optimized for single key size (8-byte, 16-byte
and 32-byte key sizes)

[Thomas: some code-style changes]
This adds the code for a new Intel DPDK library for packet distribution.
The distributor is a component which is designed to pass packets
one-at-a-time to workers, with dynamic load balancing. Using the RSS
field in the mbuf as a tag, the distributor tracks what packet tag is
being processed by what worker and then ensures that no two packets with
the same tag are in-flight simultaneously. Once a tag is not in-flight,
then the next packet with that tag will be sent to the next available
core.

# ${RTE_SDK}/x86_64-default-linuxapp-gcc directory
user@droids:~/dpdk.org$ make install T=x86_64-default-linuxapp-gcc
# build examples for this new installation in
# ${RTE_SDK}/examples directory
user@droids:~/dpdk.org$ make examples T=x86_64-default-linuxapp-gcc
- build examples outside DPDK tree for several targets
# install all targets matching x86_64-*-linuxapp-gcc in
# ${RTE_SDK}/x86_64-*-linuxapp-gcc directories
user@droids:~/dpdk.org$ make install T=x86_64-*-linuxapp-gcc

a0cdfcf9 (use pcap-config to guess compilation flags),
ef5b2363 (fix build with empty LIBPCAP_CFLAGS) and
60191b89 (fix build when pcap_sendpacket is unavailable).
These patches are creating more problems than solving the initial one
(which was a build error with too old pcap libraries).
Since old pcap libraries are not that common, just revert them.
