Podle me je 0x1 ethernet, do /proc/net/arp zapisuje obsah
net_device->type, ktery je definovan v include/linux/netdevice.h jako
    unsigned short      type;   /* interface hardware type  */
Zjistuje se to podle RFC1700,
ARPHRD_NETROM   NET/ROM(tm) devices
ARPHRD_ETHER         10 and 100Mbit/second Ethernet
ARPHRD_EETHER   Experimental Ethernet (not used)
ARPHRD_AX25          AX.25 level 2 interfaces
ARPHRD_PRONET        PROnet token ring (not used)
ARPHRD_CHAOS         ChaosNET (not used)
ARPHRD_IEE802        802.2 networks notably token ring
ARPHRD_ARCNET        ARCnet interfaces
ARPHRD_DLCI          Frame Relay DLCI
Defined by Linux:
ARPHRD_SLIP          Serial Line IP protocol
ARPHRD_CSLIP         SLIP with VJ header compression
ARPHRD_SLIP6         6bit encoded SLIP
ARPHRD_CSLIP6        6bit encoded header compressed SLIP
ARPHRD_ADAPT         SLIP interface in adaptive mode
ARPHRD_PPP      PPP interfaces (async and sync)
ARPHRD_TUNNEL   IPIP tunnels
ARPHRD_TUNNEL6  IPv6 over IP tunnels
ARPHRD_FRAD          Frame Relay Access Device
ARPHRD_SKIP          SKIP encryption tunnel
ARPHRD_LOOPBACK Loopback device
ARPHRD_LOCALTLK Localtalk apple networking device
ARPHRD_METRICOM Metricom Radio Network

Opravte me, jestli se mylim.
