10-Bit Tag capability, introduced in PCIe-4.0 increases the total Tag
field size from 8 bits to 10 bits.

This patchset is to enable 10-Bit tag for PCIe EP devices (include VF) and
RP devices.

Dongdong Liu (4):
  PCI: Add 10-Bit Tag register definitions
  PCI: Enable 10-Bit tag support for PCIe Endpoint devices
  PCI/IOV: Enable 10-Bit tag support for PCIe VF devices
  PCI: Enable 10-Bit tag support for PCIe RP devices
