-/*?
- * This command is used to start or stop a packet capture, or show
- * the status of packet capture. Note that both "pcap rx trace" and
- * "pcap tx trace" are implemented. The command syntax is identical,
- * simply substitute rx for tx as needed.
- *
- * This command has the following optional parameters:
- *
- * - <b>on|off</b> - Used to start or stop a packet capture.
- *
- * - <b>max <nn></b> - Depth of local buffer. Once '<em>nn</em>' number
- *   of packets have been received, buffer is flushed to file. Once another
- *   '<em>nn</em>' number of packets have been received, buffer is flushed
- *   to file, overwriting previous write. If not entered, value defaults
- *   to 100. Can only be updated if packet capture is off.
- *
- * - <b>intfc <interface>|any</b> - Used to specify a given interface,
- *   or use '<em>any</em>' to run packet capture on all interfaces.
- *   '<em>any</em>' is the default if not provided. Settings from a previous
- *   packet capture are preserved, so '<em>any</em>' can be used to reset
- *   the interface setting.
- *
- * - <b>file <name></b> - Used to specify the output filename. The file will
- *   be placed in the '<em>/tmp</em>' directory, so only the filename is
- *   supported. Directory should not be entered. If file already exists, file
- *   will be overwritten. If no filename is provided, '<em>/tmp/vpe.pcap</em>'
- *   will be used. Can only be updated if packet capture is off.
- *
- * - <b>status</b> - Displays the current status and configured attributes
- *   associated with a packet capture. If packet capture is in progress,
- *   '<em>status</em>' also will return the number of packets currently in
- *   the local buffer. All additional attributes entered on command line
- *   with '<em>status</em>' will be ignored and not applied.
- *
- * @cliexpar
- * Example of how to display the status of a tx packet capture when off:
- * @cliexstart{pcap tx trace status}
- * max is 100, for any interface to file /tmp/vpe.pcap
- * pcap tx capture is off...
- * @cliexend
- * Example of how to start a tx packet capture:
- * @cliexstart{pcap tx trace on max 35 intfc GigabitEthernet0/8/0 file vppTest.pcap}
- * pcap tx capture on...
- * @cliexend
- * Example of how to display the status of a tx packet capture in progress:
- * @cliexstart{pcap tx trace status}
- * max is 35, for interface GigabitEthernet0/8/0 to file /tmp/vppTest.pcap
- * pcap tx capture is on: 20 of 35 pkts...
- * @cliexend
- * Example of how to stop a tx packet capture:
- * @cliexstart{vppctl pcap tx trace off}
- * captured 21 pkts...
- * saved to /tmp/vppTest.pcap...
- * @cliexend
