 * How many bytes should we examine on every packet that comes off the
 * wire?  This doesn't include the link layer which is accounted for
 * later.  We're looking only for ICMP and TCP packets, so this should
 * work.  For ICMP, we also examine the quoted IP header, which is why
 * there's a *2 there.  The +32 is just to be safe.
