+Set capture buffer size (in MB, default is 1MB).  This is used by the
+the capture driver to buffer packet data until that data can be written

+this size.  Note that, while B<Tshark> attempts to set the buffer size
+to 1MB by default, and can be told to set it to a larger value, the
+system or interface on which you're capturing might silently limit the
+capture buffer size to a lower value or raise it to a higher value.

+This is available on on UNIX systems with libpcap 1.0.0 or later and on
+Windows.  It is not available on UNIX systems with earlier versions of
