getFlowKeyForPacket

public static java.lang.String getFlowKeyForPacket(VNSPacket p)

Finds the ClackOccData object that corresponds to the flow for this particular packet. Creates a new data object if needed. If the packet is not UDP or TCP, the NON_FLOW data object is returned. WARNING: This packet must be called with an IP packet or Ethernet packet
