table: fix checking extended buckets in unoptimized case
If a key is not found in a bucket and the bucket has been extended,
the extended buckets also have to checked for potentially matching
keys. The extended buckets are checked at the end of the lookup. In
most cases, this logic is skipped as it is uncommon to have buckets in
an extended state.
In case the lookup is performed with less than 5 packets, an
unoptimized version is run instead (the optimized version requires at
least 5 packets). The extended buckets should also be checked in this
case instead of simply ignoring the extended buckets.
table: fix empty bucket removal during entry deletion
When an entry is deleted from an extensible rte_table_hash, the bucket
that stored the entry can become empty. If this is the case, the
bucket needs to be removed from the chain of buckets.
During removal of the bucket, the chain should be updated first. If
the bucket that will be removed is cleared first, the chain is broken
and the information to update the chain is lost.

examples/distributor: new sample app
A new sample app that shows the usage of the distributor library. This
app works as follows:
* An RX thread runs which pulls packets from each ethernet port in turn
and passes those packets to worker using a distributor component.
* The workers take the packets in turn, and determine the output port
for those packets using basic l2forwarding doing an xor on the source
port id.
* The RX thread takes the returned packets from the workers and enqueue
those packets into an rte_ring structure.
* A TX thread pulls the packets off the rte_ring structure and then
sends each packet out the output port specified previously by the worker
* Command-line option support provided only for portmask.

vmxnet3: leverage data ring on Tx path
Data_ring is a pre-mapped guest ring buffer that vmxnet3
backend has access to directly without a need for buffer
address mapping and unmapping during packet transmission.
It is useful in reducing device emulation cost on the tx
path. There are some additional cost though on the guest
driver for packet copy and overall it's a win.
This patch leverages the data_ring for packets with a
length less than or equal to the data_ring entry size
(128B). For larger packet, we won't use the data_ring
as that requires one extra tx descriptor and it's not
clear if doing this will be beneficial.
Performance results show that this patch significantly
boosts vmxnet3 64B tx performance (pkt rate) for l2fwd
application on a Ivy Bridge server by >20% at which
point we start to hit some bottleneck on the rx side.

vmxnet3: improve Rx performance
This patch includes two small performance optimizations
on the rx path:
(1) It adds unlikely hints on various infrequent error
paths to the compiler to make branch prediction more
efficient.
(2) It also moves a constant assignment out of the pkt
polling loop. This saves one branching per packet.
Performance evaluation configs:
- On the DPDK-side, it's running some l3 forwarding app
inside a VM on ESXi with one core assigned for polling.
- On the client side, pktgen/dpdk is used to generate
64B tcp packets at line rate (14.8M PPS).
Performance results on a Nehalem box (4cores@2.8GHzx2)
shown below. CPU usage is collected factoring out the
idle loop cost.
- Before the patch, ~900K PPS with 65% CPU of a core
used for DPDK.
- After the patch, only 45% of a core used, while
maintaining the same packet rate.

app/test: measure cycles per packet in Rx/Tx
The unit test can be used to measure cycles per packet in different rx/tx routines.
The NIC works in loopback mode. So it doesn't require test equipment to measure throughput.
As result, the unit test shows the average cycles per packet consuming.
When doing the test, make sure the link is UP.
Usage Example:
1. Run unit test app in interactive mode
app/test -c f -n 4 -- -i
2. Run and wait for the result
pmd_perf_autotest
There's option to choose rx/tx pair, default is vector.
set_rxtx_mode [vector|scalar|full|hybrid]
Note: To get acurate scalar fast, please choose 'vector' or 'hybrid' without INC_VEC=y in config
It supports to measure standalone rx or tx.
Usage Example:
Choose rx or tx standalone, default is both
set_rxtx_anchor [rxtx|rxonly|txonly]
It also supports to measure standalone RX burst cycles.
In this way, it won't repeat re-send received packets.
Now it measures two situations, poll before/after xmit(w or w/o desc. cache conflict)
Usage Example:
Set stream control mode, by default is continuous

ethdev: UDP tunnels
Add two functions to support UDP tunneling port configuration.
There are "some" destination UDP port numbers that have unique meaning.
In terms of VxLAN, "IANA has assigned the value 4789 for the VXLAN UDP port,
and this value SHOULD be used by default as the destination UDP port.
Some early implementations of VXLAN have used other values for the destination
port. To enable interoperability with these implementations, the destination
port SHOULD be configurable."
