Re: [Xen-devel] [PATCH] Network Checksum Removal

[Keir Fraser <Keir.Fraser@xxxxxxxxxxxx>]

I think I found the problem, and I've checked in a fix.

Bin: can you try dom0->domU networking with latest unstable tree? 
Hopefully your problem is fixed.
As further work on this, I think I chose a bad name for the 
'proto_csum_valid' field because sometimes it is set for local packets 
that have had no csum poked into the packet at all. Something like 
'proto_data_valid' might be better. And communicating this information 
between domains (i.e., that the csum field is blank, but the packet 
data is known good anyway) would be nice. Then domU can decide to add 
the checksum if it passes the packet off to a context that expects a 
valid checksum.
