[Xen-devel] PCIe 2.0, VT-d and Intel 82576 enhancement for Xen SR-IOV

[Yu Zhao <yu.zhao@xxxxxxxxx>]

Greetings,

Following patches enhance the VT-d and PCI code, and add a quirk for
Intel 82576 SR-IOV NIC, so they can work better with the SR-IOV core.

  PCI: pass ARI and SR-IOV device information to the hypervisor
  PCI: add a SR-IOV quirk for Intel 82576 NIC
  PCI: save and restore PCIe 2.0 registers
