I and also other people had some patches to move the time stamp
measuring into the socket. This way the time stamping didn't need to
be enabled on all packets, only on those that actually end up at a
socket that requires the time stamp.

Unfortunately DaveM didn't like it because some bank wanted
different semantics, see the discussion in 
http://thread.gmane.org/gmane.linux.network/91679

Perhaps you can find out which bank it was and send them a bill for
your CPU time ;-)
