I had to put this aside for awhile, but revisited it today.  While I did change
the filter to one of the form "{expr} {relop} {expr}" and was able to
successfully capture packets, the capture filter itself doesn't really seem to
do much of anything.  Basically what I've found is that as long as you have a
valid filter specified, ALL packets are captured regardless of what the filter
is.  However, if I apply the same exact filter when reading a previously saved
capture file, then the filter works as expected.  Has anyone else experienced
this?
