[Xen-devel] Re: Xen TCP/UDP checksum problems

[Tim Durack <tdurack@xxxxxxxxx>]

It seems to be driver related. Anything tg3/bcm broadcom based.

 

A bridged setup doesn't exhibit the problem.

 

A routed setup has tcp/udp checksum problems. You can make routed work by building gre tunnels on top of the eth0/vifx.1 virtual point-to-point links. These extra encapsulation seems to avoid whatever the checksum offload problem is. Ugly but it works.

 

Sorry I don't have anything better to offer.
