* 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

* This command is used to set the packet fields required for classifying the
* incoming packet. As a result of classification process, packet field

* color) and stored in packet mbuf.
*
* This command has the following parameters:
*
* - <b><interface></b> - Used to specify the output interface.
*
* - <b>id subport|pipe|tc</b> - Classification occurs across three fields.
* This parameter indicates which of the three masks are being configured. Legacy
* code used 0-2 to represent these three fields, so 0-2 is still accepted.
* - <b>subport|0</b> - Currently only one subport is supported, so only
* an empty mask is supported for the subport classification.
* - <b>pipe|1</b> - Currently, 4096 pipes per subport are supported, so a
* 12-bit mask should be configure to map to the 0-4095 pipes.
* - <b>tc|2</b> - The translation table (see '<em>set dpdk interface hqos
* tctbl</em>' command) maps each value (0-63) into one of the 4 traffic classes
* per pipe. A 6-bit mask should be configure to map this field to a traffic class.
*
* - <b>offset <n></b> - Offset in the packet to apply the 64-bit mask for classification.
* The offset should be on an 8-byte boundary (0,8,16,24..).
*
* - <b>mask <hex-mask></b> - 64-bit mask to apply to packet at the given '<em>offset</em>'.
* Bits must be contiguous and should not include '<em>0x</em>'.
*
* The default values for the '<em>pktfield</em>' assumes Ethernet/IPv4/UDP packets with
* no VLAN. Adjust based on expected packet format and desired classification field.
* - '<em>subport</em>' is always empty (offset 0 mask 0000000000000000)
* - By default, '<em>pipe</em>' maps to the UDP payload bits 12 .. 23 (offset 40
* mask 0000000fff000000)
* - By default, '<em>tc</em>' maps to the DSCP field in IP header (offset 48 mask
