Patch for trimming interface line
by kovacsbalu, November 30, 2011
When you have longer interface names (eg. vboxnet0) the result always was 0Kb/s because @splitinterface first item was empty.

Useful, needs two small corrections
by ammilligan, May 31, 2010
Works as described, but needs two corrections to report outbound network utilizations.

Correction 1.
Change line 119 from this:
if ($in_rate >= $opt_w && $in_rate = $opt_w && $out_rate = $opt_c )
to this:
elsif ($out_rate >= $opt_c )
