The function rte_eth_dev_allocate() was called by rte_eth_dev_init().
In order to use it for non-pci devices, it is now in public API.

This type of pseudo-device is needed for ring and pcap PMDs.
They are compatible with whitelist and are initialized in rte_eal_init().

In case of multi-process application, the secondary process can initialize
the driver without configuring queues. In this case the Rx/Tx functions
were not initialized because it was only done in queue setup.
Fix by reproducing the same behaviour as in eth_ixgbe_dev_init().

rte_malloc try to allocate memzone blocks with a minimum size.
It it fails, it retries for a smaller size than the standard one.
It will really fail if it cannot allocate block of the requested size.

The pause instruction is part of SSE2 extensions.
Note that some compilers define _mm_pause as "rep; nop" instead of "pause".
For compatible processors, they are equivalent.

"
When executing a spin-wait loop, a Pentium 4 or Intel Xeon processor suffers
a severe performance penalty when exiting the loop because it detects a
possible memory order violation.
The PAUSE instruction provides a hint to the processor that the code sequence
is a spin-wait loop. The processor uses this hint to avoid the memory order
violation in most situations, which greatly improves processor performance.

- timecompare (used for hardware timestamping) has been removed.
(see Linux commit 65f8f9a1c1db831e5159e3e3e50912d1f214cd0c)
Simply disable HW_TIME_STAMP feature because it is not used by KNI.
- annotations __devinit and __devexit have been removed.
