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?
