* [sflow + dropmon] added INCLUDE_SFLOW_DROPMON flag, added patches for hsflowd *Added a capability of monitoring dropped packets for the sFlow daemon in order to improve network - monitoring, diagnostic, and troubleshooting. The drop monitor service allows the sFlow daemon to export another type of sample - dropped packets as Discard samples alongside Counter samples and Packet Flow samples.
