   Be careful with this.  tcpdump has changed behavior at least two times
in as many years.  Originally it would set the interface to promiscuous,
and '-p' told it not to.  Then it was changed, somewhere around v3.4, so
that it didn't force promiscuous UNLESS you used '-p'.  Now, at version 
3.6 (RedHat 7.2), the original behavior is back.  The bright side is that 
through the changes the man page has been an accurate reference.
