  DATAPATH DEBUGGING COMMANDS
These commands query and modify datapaths. They are are similar to ovs-dpctl(8) commands. dpif/show has the additional functionality, beyond dpctl/show of printing OpenFlow port numbers. The other commands are redundant and will be removed in a future release.

dpif/dump-dps
    Prints the name of each configured datapath on a separate line.

dpif/show
    Prints a summary of configured datapaths, including statistics and a list of connected ports. The port information includes the OpenFlow port number, datapath port number, and the type. (The local port is identified as OpenFlow port 65534.)

dpif/dump-flows [-m] dp
    Prints to the console all flow entries in datapath dp's flow table. Without -m, output omits match fields that a flow wildcards entirely; with -m output includes all wildcarded fields.

    This command is primarily useful for debugging Open vSwitch. The flow table entries that it displays are not OpenFlow flow entries. Instead, they are different and considerably simpler flows maintained by the datapath module. If you wish to see the OpenFlow flow entries, use ovs-ofctl dump-flows.

dpif/del-flows dp
    Deletes all flow entries from datapath dp's flow table and underlying datapath implementation (e.g., kernel datapath module).

    This command is primarily useful for debugging Open vSwitch. As discussed in dpif/dump-flows, these entries are not OpenFlow flow entries.
