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

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.

It's via the new vif0.0/veth0. I did tcpdump on vif1.0 in dom0 and saw
packets sent by dom0, but got dropped by the netfront on dom1.
