   - Added ixgbe_hw.rx_bulk_alloc_allowed - see ixgbe_hw.rx_vec_allowed description below.
   - Added ixgbe_hw.rx_vec_allowed: like with Bulk Allocation, Vector Rx is

         - Vector Rx specific preconditions.
         - Bulk Allocation preconditions.

and the corresponding module is not loaded, then exit, otherwise, just report a warning,

eal: clean up export of socket id variable

Theres no need to export this variable.  Its set and queried from an API call
that doesn't exist in the hot path.  Instead just export the rte_socket_id
symbol and make the variable private to protect it from type changes.  We should
do this with the other exported variables too, but I think its too late in the
release cycle to do that.

tested using distributor_autotest (which uses rte_socket_id), successfully.
Only tested on linux, as I don't currently have a bsd system spun up, but the
changes are symmetric, and should be fine

null: new poll mode driver

Null PMD is a driver of the virtual device particularly designed to measure
performance of DPDK PMDs. When an application call rx, Null PMD just allocates
mbufs and returns those. Also tx, the PMD just frees mbufs.

The PMD has following options.
- size: specify packe size allocated by RX. Default packet size is 64.
- copy: specify 1 or 0 to enable or disable copy while RX and TX.
Default value is 0(disabled).
This option is used for emulating more realistic data transfer.
Copy size is equal to packet size.

To use the PMD, enable CONFIG_RTE_BUILD_SHARED_LIB in config file. Then
compile the PMD as shared library. The library can be linked using '-d'
option when an application invokes.

Here is an example.
$ sudo ./testpmd -c f -n 4 -d librte_pmd_null.so \
--vdev 'eth_null0' --vdev 'eth_null1' -- -i --no-flush-rx

If testpmd is compiled with CONFIG_RTE_BUILD_SHARED_LIB, it may need to
specify more libraries using '-d' option.
