limit not bandwith, but packets per second in linux
tc with all its qdiscs is perfect way to limibandwith, but is there any means in linux to limit pps

why i ask it.
normally you think about only one resource - bandwith, but when some app starts to generate tremendous amount of small packets (for instance http get requests which are containing reletevly small amount of byres in it) then probably pps will be the resource.

i came across these solution
netfilter ipchains and user space app.
