[P4] L3FWD p4-16-on?

[Tejfel Máté]

Sziasztok!

   Közben rájöttünk, hogy csak az volt a gond, hogy az átnevezések miatt 
nem volt bejegyzés az l3-routing-full-ra a config fájlban... Egy 
átnevezéssel megoldottuk a gondot...

Robi arra nem tudnánk kicsit egyértelműbb hibajelzést adni, ha valami 
hiányzik teljesen a configból?

     M.
