That's the one I was trying to remember, but I didn't compose a good  
query and couldn't find it.

IIRC the NIC timestamps arriving packets right off the wire?   We have  
an on-chip logic analyzer
gadget that can do that, but the synchronization problem we have is  
only to find one-time
offsets, so we didn't need to go this deep.
