   This sounded so unbelievable to me that I took a quick look at the code to
   see what I'd have to do to get rid of it.  It appears that gettimeofday is
   not called for every packet; just for ICMP timestamp requests and for IP
   options (ip_options_build and ip_options_compile).

Stop lookin in the IP code.  Look at where we get the packet
from the device, which is one layer up.
