iptraf uses device names to determine the device type:

char ifaces[][6] =
     { "lo", "eth", "sl", "ppp", "ippp", "plip", "fddi", "isdn", "dvb",
     "pvc", "hdlc", "ipsec", "sbni", "tr", "wvlan", "wlan", "sm2", "sm3",
     "pent", "lec", "brg", "tun", "tap", "cipcb", "tunl", "vlan", "ath",
     "ra"
};

and

         if (strncmp(ifname, "eth", 3) == 0)
             result = LINK_ETHERNET;
         else if (strncmp(ifname, "ath", 3) == 0)
             result = LINK_ETHERNET;
         else if (strncmp(ifname, "plip", 4) == 0)
             result = LINK_PLIP;
