You only need this between the driver and the socket recvmsg(), don't you?

One possible alternative (I admit I haven't thought all the implications
through) would be to use a second magic internal skb for this which has the 
same UDP header, but as only payload the time stamp. Disadvantage would
be the requirement to do header parsing in the driver, but often
hardware does that already.
