Hi,
Here's a few patches to fix virtio_net GSO
and partial csum support under older kernels.
Applied all, thanks. Sorry for the virtio-like latency in processing.
I don't much like the intense hackery involved in this. The way I think
it could be done is:
- hack virtio to use an API which is specific to kvm, but matches the
current upstream API:
s/net_func/virtio_compat_net_func/
including data structures.
- define this API on top of the host kernel's real API. For a recent
enough kernel, that's a one-to-one mapping:
virtio_compat_net_func() { return net_func(); }
for older ones there's a more trickery involved.
For kvm, this is a fairly successful strategy, but I imagine that for
virtio-net this will be much, much, more difficult.
- write Documentation/stable_api_nonsense_nonsense.txt.

I have a truly marvellous patch that fixes the bug which this
