I have never used it but there is a kernel module that calls himself
"Packet Generator" and warns "Use with care"
 Symbol: NET_PKTGEN [=m] 

  Prompt: Packet Generator (USE WITH CAUTION) 

   Defined at net/Kconfig:615 

	Depends on: NET && PROC_FS 

	Location: 

	-> Device Drivers 

	 -> Networking support 

	  -> Networking support (NET [=y]) 

	   -> Networking options 

            -> Network testing
Seems you can go on reading
file:Documentation/networking/pktgen.txt
