Linux Virtualization - Jun 2010 - [PATCH 0/3][STABLE] KVM: Various issues in virtio_net

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 at kernel.org myself; please add the following two lines to the last one
and repost to netdev at vger.kernel.org.
