bitkeeper revision 1.1516 (4292225caWyLsfo-mZ3yV4QmUhXSAQ)
Fix the veth0/vif0.0 loopback interfaces to properly assert integrity
of locally-generated packets. Hopefully this will fix dom0->domU
communications. As an aside, I think 'proto_csum_valid' is not a good
name for that field -- I may rename to 'proto_data_valid' or something
like that.
