Takze zda se, ze prijem funguje, kdyz dam pevnou IP prijme smysluplny 
paket treba pri PING a asi se snazi odpovedet - ale to uz nic... Asi 
nejde vysilani - ale fyzicky asi ano, kdyz PHY nedetekuje zadnou chybu 
pro Auto-negotiation? Tam predpokladam musi fyzicky komunikovat. Takze 
zbyva interface mezi CPU a PHY??? To zas bude nejaka kravina, uz jsem 
vsechno projel lupou 10x a QFN LAN8710 i znova zapajel (jiny), divne. 
Mozna jeste neco v nastaveni PHY?
