Merge branch 'pci/enumeration'

Browse source 
- add decoding for 16 GT/s link speed (Jay Fang)

  - add interfaces to get max link speed and width (Tal Gilboa)

  - add pcie_bandwidth_capable() to compute max supported link bandwidth
    (Tal Gilboa)

  - add pcie_bandwidth_available() to compute bandwidth available to device
    (Tal Gilboa)

  - add pcie_print_link_status() to log link speed and whether it's limited
    (Tal Gilboa)

  - use PCI core interfaces to report when device performance may be
    limited by its slot instead of doing it in each driver (Tal Gilboa)

* pci/enumeration:
  fm10k: Report PCIe link properties with pcie_print_link_status()
  net/mlx5e: Use pcie_bandwidth_available() to compute bandwidth
  net/mlx5: Report PCIe link properties with pcie_print_link_status()
  net/mlx4_core: Report PCIe link properties with pcie_print_link_status()
  PCI: Add pcie_print_link_status() to log link speed and whether it's limited
  PCI: Add pcie_bandwidth_available() to compute bandwidth available to device
  PCI: Add pcie_bandwidth_capable() to compute max supported link bandwidth
  PCI: Add pcie_get_width_cap() to find max supported link width
  PCI: Add pcie_get_speed_cap() to find max supported link speed
  PCI: Add decoding for 16 GT/s link speed
