Random PDU Generator
Sends a random PDU once at startup and then every time it receives a message.
Note for 3.10 This block has been moved from gr-blocks to gr-pdu, which causes a name change of the id. See Porting_Existing_Flowgraphs_to_a_Newer_Version#PDU_blocks_moved_from_gr-blocks_to_gr-pdu for details.

- Max Bytes
