Please send virtio patches, including patches for the stable branches, 
to the virtio maintainer (Rusty).  Copying Michael (mst@redhat.com) is 
also a good idea.

Also:

- use git format-patch/git sent-email or equivalents; these ensure the 
correct formatting and group the patches together for threaded mail clients
- indicate the upstream commit (often it's enough to ask the maintainers 
to backport a commit)

[PATCH 0/3][STABLE] KVM: Various issues in virtio_net

[Bruce Rogers]

These are patches which we have found useful for our 2.6.32 based SLES 11 SP1 release. 

The first patch is already upstream, but should be included in 2.6.32 stable tree.

The second patch is a subset of another upstream patch. Again, stable material, applicable to 2.6.32 and 2.6.33.

The third patch solves the last remaining issue we saw when testing kvm configurations with the SUSE certification test suite. Under heavy load, we observed rx stalls (first two patches applied), and this third patch was crafted to address the issue. Please apply to 2.6.32, 2.6.33, and 2.6.34 stable trees.
(I assume this last problem also exists in more recent kernels than 2.6.32, but I haven't validated that.)

With these 3 patches applied we no longer see any issues with virito networking using our certification test suite.

Hi Bruce, thanks for these.

netdev is the right place for these patches.  I'll send the first two to
stable@kernel.org myself; please add the following two lines to the last one
and repost to netdev@vger.kernel.org.

Acked-by: Rusty Russell <rusty@rustcorp.com.au>
Cc: stable@kernel.org

Thanks!
Rusty.

These are patches which we have found useful for our 2.6.32 based SLES 11 SP1 release. 

The first patch is already upstream, but should be included in stable.

The second patch is a subset of another upstream patch. Again, stable material.

The third patch solves the last remaining issue we saw when testing kvm configurations with the SUSE certification test suite. Under heavy load, we observed rx stalls (first two patches applied), and this third patch was crafted to address the issue. Please apply to stable.
I assume this last problem also exists in more recent kernels than 2.6.32, but I haven't validated that.

With these 3 patches applied we no longer see any issues with virito networking using our certification test suite.
