The first patch adds NPAR 1.2 support.  Patches 2 to 10 add TPH
(TLP Processing Hints) support.  These TPH driver patches are new
revisions originally posted as part of the TPH PCI patch series.
Additional driver refactoring has been done so that we can free
and allocate RX completion ring and the TX rings if the channel is
a combined channel.  We also add napi_disable() and napi_enable()
during queue_stop() and queue_start() respectively, and reset for
error handling in queue_start().

v4:
Fix NPAR typo in patch #1 and improve the description of NPAR

v3:
Fix build bot warning in patch #9
Add MODULE_IMPORT_NS("NETDEV_INTERNAL") to patch #10
Optimize ring operations when TPH is not enabled in patch #8 and #9

v2:
Major change is error handling in patch #9.
