The "best" formula that I've (personally) seen will accommodate for the
preamble and the interpacket gap.  Algebraically, it goes:

   #packets * (9.6 + 6.4)   +  #octets * 0.8
   ----------------------------------------------------------
               Interval * 10000

and should result in a value in the range of 0 - 100.  I have also coded a
MIB expression for it, which looks like:

EtherUtil \
"Ethernet Utilization" \
                .1.3.6.1.2.1.16.1.1.1.5.        \
                16 *                    \
                .1.3.6.1.2.1.16.1.1.1.4.        \
                0.8 * +                 \
                10000 /


This should be directly placeable in MibExpr.conf
