Limit PPS for UDP Traffic

[mdes]

@belt9:

Exactly what UDP traffic problems are you having?

Since PF and consequently pfSense lack limit pps for UDP feature, I had to do it on an upstream router.
Well I think, unless proper MAC filtering, NetFlow MAC exporting and UDP PPS limiting is implemented, I cannot use pfSense for my customers (SMB and small enterprises).
It has many great features and I really appreciate all work that developers have done.
