Hi,

This series adds SR-IOV PF pmd driver support to have VF pmd
driver work over PF pmd driver instances in order to run the
adapter completely under DPDK environment for one of the use
cases like ovs-dpdk.

This is very initial bring-up with following testing covered -

* Enable/Disable SR-IOV VFs through igb_uio sysfs hook.
* Load VFs, run fastpath, teardown VFs in hypervisor and guest VM.
* VF FLR flow (in case of VF PCI passthrough to the guest VM)
* Bulletin mechanism tested to communicate link changes to the VFs.

Note that this series is intended for upcoming DPDK release (20.08)
Please consider applying this series to dpdk-next-net-mrvl.git

V3->V4:
=======

* Fixed meson/ninja build failure for AMD arch.
* Incorporated cosmetic changes pointed by Gaetan.

V2->V3:
=======

* Instead of adding complete pci_regs.h file from linux, define handful
  PCI symbols (prefixed with RTE_) in dpdk which are required to implement
  generic rte_pci_find_next_ext_capability() API (patch #1) and to enable
  various other qede driver's OSAL_* defines (patch #2)
  (essentially, removed the patch #1 in v2)

* Fixed meson/ninja compilation issues reported

* Incorporated comments by Gaetan for rte_pci_find_next_ext_capability()

V1->V2: (Incorporated comments from Jerin Jacob)
================================================

* Added rte_pci_regs.h file (copy of linux/pci_regs.h) under
  lib/librte_pci to remove the dependency of dpdk on user headers

* Added generic API to find PCI extended capability and use
  that in the drivers, removed individual functions implemented
  by the drivers

Thanks,
Manish
