Toto snad chápu: Well, it's just non-ip traffic, like netbui(M$ crap protocol not running over IP), or SNA
Je to obyčejné HW APčko a všechny zbytečnosti jsou na tom vypnuté. Nevím o žádné zapnuté službě čico co by na tom navíc běželo.

Pokud cislo 0x4 je EtherType, tak se jedna o IEEE802.3 Length Field "protokol". Jenze to ma byt 16b cislo. Mozna se ale nejedna o 802.2 EtherType polozku, ale neco jineho na vyssi vrstve.
