Description Mark van Dijk 2012-09-22 17:10:03 UTC
The Xen networking device (xn0) is available when the XENHVM kernel has been compiled. The following message is flooded to dmesg:

xn_txeof: WARNING: response is -1!

I don't notice any degraded network performance.

The following options are enabled (and should be supported by Xen):
options=503<RXCSUM,TXCSUM,TSO4,LRO>

Fix: 

Not sure if it is even a problem. Maybe the warning should just be removed.
