- 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.

When in 'normal' mode, hardware is designed to receive up to 1522 bytes.
When in 'jumbo' mode, RLPML register must be updated so that hardware accepts
a 802.1q vlan header. If dual vlan is enabled, then a second vlan header is
expected, so update RLPML register according to dual vlan support.

The 82576 has known issues which require the write threshold to be set to 1.

If not then single packets will hang in transmit ring until more arrive.
Simple tests like ping will fail.

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
have none.

In many application there are no timers queued, and the call to
rte_timer_managecan be optimized in that case avoid reading HPET and
lock overhead.

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.
