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.

When blacklisting network adapters that share a PCI bus address with multiple
ports such as Mellanox ConnectX-3 (librte_pmd_mlx4), RTE applications
enter infinite loops while probing PCI devices.
This commit removes this probe on subsequent instances for blacklisted devices
that have RTE_PCI_DRV_MULTIPLE set.

Some devices like VMXNET3 have multiple PCI memory regions, and some

Introduce new option --vmware-tsc-map, ignored if
CONFIG_RTE_LIBRTE_EAL_VMWARE_TSC_MAP_SUPPORT is not set.
Default is CONFIG_RTE_LIBRTE_EAL_VMWARE_TSC_MAP_SUPPORT=y.
if CONFIG_RTE_LIBRTE_EAL_VMWARE_TSC_MAP_SUPPORT is set:
rte_rdtsc() selects at runtime between Vmware mapping of
TSC or native TSC
else
rte_rdtsc() always uses native rdtsc.
When running DPDK on VMware guest, enable --vmware-tsc-map to
read the physical TSC.
Caution: ESXi should pass monitor_control.pseudo_perfctr = TRUE
othewise it results in general protection fault.

Drivers with the flag RTE_PCI_DRV_MULTIPLE enabled will be bound several
times to the same device until they return an error.
These drivers must internally keep track of each device state in order for
this to work reliably.
This flag currently required for Ethernet adapters with several physical
ports but a single address on the PCI bus.

The returned value of lseek is a virtual address
which can be different from the offset.
Indeed, if the return address has a 64-bit canonical form,
the 16 higher bits are all 1 if bit 47 is 1.
So the check was wrong. It is better to test against an error value.
