2.6.38 includes support for macvlan/macvtap 'passthru' mode that allows
assigning
SR-IOV VFs to a KVM guest via macvtap/virtio.
It is not possible to support live migration using direct assignment of
VF's to a guest,
but 'passthu' assignment makes this possible.

Enabling this feature requires the following patch to iproute2 that
allows creating macvlan
device in 'passthru' mode.
http://patchwork.ozlabs.org/patch/69515/
Looks like this patch is still marked as 'Awaiting upstream'.

Could you apply this patch and it would be great if a version of
iproute2 is released for 2.6.38.

Thanks
Sridhar

Sorry missed it applied to repository, still not sure worth a new release.

Release early, release often. And someone actually bothered asking you to
specifically, so it clearly is going to be useful to that someone.

So, why not do a 2.6.38 release?

Indeed, Stephen please make a release.
