| Thread-topic: | bridge interaction when adding a new vif with offload options disabled |
I was trying to figure out why my DomU isn't getting large packets... It seems that when the new vif is added to the bridge on DomU init, the bridge interface disables tso, sg, and tx offloads. When the vif is eventually configured by the DomU, these are enabled on the vif but the bridge doesn't enabled tso and sg again - I have to do that manually. I've only tested this on HVM with PV drivers. No tap interface is involved. It probably sounds like a Linux bug but I thought I'd ask here first...
