If that's possible that sounds great.  However, the PARTIAL flag is per skb
so I can't see how you could find out whether a specific packet requires 
checksumming by querying the socket....  I must have missed something :-)

The option to switch to reception via AF_INET sockets also works.  Presumably on 
the client you still need AF_PACKET in order to send a datagram with source IP 
0.0.0.0, but if everyone is using AF_INET for reception, then the partial 
checksum problem should go away.

Do you know when the fix is likely to make it into the source?
