Good day,
What are the recommended offload settings for ethernet devices in Xen domUs?  I assume they should all bet set to off?
Here is what is set by default currently in our domUs:
Offload parameters for eth0:
Cannot get device rx csum settings: Operation not supported
Cannot get device udp large send offload settings: Operation not supported
rx-checksumming: off
tx-checksumming: on
scatter-gather: on
tcp segmentation offload: on
udp fragmentation offload: off
generic segmentation offload: off
