I created an IP trace dump by listening on an Android phone's mobile data
interface using and old version of libpcap which someone ported to Android
(http://sourceforge.net/p/prueba-android/code/HEAD/tree/trunk/jni/).
The link layer type of the packets is SLL (i.e. linux cooked capture). The
captured SLL headers contain valid values according to
http://www.tcpdump.org/linktypes/LINKTYPE_LINUX_SLL.html. But when opening the
dump in Wireshark it misinterprets the link layer type as Ethernet II (and it
seems I can't even force Wireshark to interpret it as SLL).
The sample SLL capture file from https://wiki.wireshark.org/SLL is interpreted
and parsed correctly by wireshark. The only differences in the SLL header
between my captures and the sample are the fields: ARPHRD_ type, Link-layer
address length and Link-layer address.
