[Tejfel Máté]

Néztük megbeszélésen... Horpácsi Dani magára vállalta a feladatot, hogy 
felveszi vele a kapcsolatot, mivel van közös ismerősük :) M.

> To help me get a better understanding of T4P4S I'd like to ask a few 
> quick questions:
> 1. Can T4P4S compile any P4 program to run over DPDK, or does it only 
> support a supset of P4 program features?
> 2. Does T4P4S support P4 extern functions and/or extern objects? Given 
> that these functions are typically written in something like C, is it 
> straightforward to compile/link them together with the output 
> generated by T4P4S?
> 3. What are T4P4S limitations?
> 4. Has T4P4S been used externally to ELTE before, as part of somebody 
> else's research project?
