[P4] Fwd: Re: P4-es dolgok

Update:
A log további nézegetése során rájöttem, hogy egyrészt a nop jó, mert az
smac táblát valóban nop-pal töltjük fel, de a dmac tábla nem töltődik fel
mert:
[NO-CORE] MSG from controller 104 dmac
[NO-CORE] Table add entry: table name mismatch (dmac).
Nincs dmac nevű táblánk?

Üdv,
Peti
