table: fix pointer calculations at initialization

contiguous region of memory is allocated to store meta data, buckets,
extended buckets, keys, stack of keys, stack of extended buckets and
data entries. The size of each region depends on the hash table
configuration.

The address of each region is calculated using offsets relative to the
beginning of the memory region. Without this patch, the offsets
contain the size of the table meta data (sizeof(struct
rte_table_hash)). These addresses are stored in pointers which are
used when entries are added or deleted and lookups are performed.

Instead of adding these offsets to the address of the beginning of the
memory region, they are added to the address of the end of the meta
data (= address of the beginning of the memory region + sizeof(struct
rte_table_hash)). The resulting addresses are off by sizeof(struct
rte_table_hash) bytes. As a consequence, memory past the allocated
region can be accessed by the add, delete and lookup operations.

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

(2) It also moves a constant assignment out of the pkt

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

    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:

examples/vmdq: use new VMDQ API

This patch supports new VMDQ API in vmdq example.
Besides, it allows users to specify num_pools different with
max_nb_pools, thus the polling thread needn't to poll queues
of all pools.

Due to i40e implementation issue, there is no default mac for
VMDQ pool, so app needs to specify mac address for each pool
explicitly.
