Greetings,

Following patches are intended to support SR-IOV capability in the
Linux kernel. With these patches, people can turn a PCI device with
the capability into multiple ones from software perspective, which
will benefit KVM and achieve other purposes such as QoS, security,
and etc.

SR-IOV specification can be found at:
http://www.pcisig.com/members/downloads/specifications/iov/sr-iov1.0_11Sep07.pdf
(it requires membership.)

Devices that support SR-IOV are available from following vendors:

Physical Function driver patches for Intel 82576 NIC are available:

http://patchwork.kernel.org/patch/8064/
http://patchwork.kernel.org/patch/8065/

Major changes from v9 to v10:
1, minor fix in pci_restore_iov_state().
2, respin against the latest tree.
