Thanks for the continued help fixing this!

I couldn't reproduce it using redis-benchmark on EC2, but that's okay.

Scatter/gather IO is solely a performance flag in the driver? As in, it won't affect applications?

The only effect I noticed after disabling it is that it's apparently required for jumbo framing:

    vif vif-0 eth0: Reducing MTU because no SG offload

And it dropped to 1500. But I can live with that.

Also, do you have a link to the upstream discussion?
