[Xen-devel] Request for backport of 82599 quirks to 3.4.2

["Rose, Gregory V" <gregory.v.rose@xxxxxxxxx>]

Keir,
 
I'd like to request that changset 
http://xenbits.xensource.com/xen-unstable.hg?rev/091209f1b95c from xen unstable 
be backported to the 3.4.2 release.
 
Ian,
 
I would also need the changes to pass-through.c in qemu backported.  The git 
commit is a77dc89dde1b8b9331c0f746e34389d6a253755f from Aug. 4.

    passthrough: support the assignment of the VF of Intel 82599 10GbE Controlle
    
    The datasheet is available at
    http://download.intel.com/design/network/datashts/82599_datasheet.pdf
    
    See 'Table 9.7. VF PCIe Configuration Space' of the datasheet, the PCI
    Express Capability Structure of the VF of Intel 82599 10GbE Controller looks
    trivial, e.g., the PCI Express Capabilities Register is 0, so the Capability
    Version is 0 and pt_pcie_size_init() would fail.
    
    We should not try to expose the PCIe cap of the device to guest.

This will allow us and other interested parties to develop and test our 82599 
10Gbe adapters on Xen 3.4.2 stable when it becomes available.

Thanks,
