"Identifies" in what sense?
As in returns 3 as an identifier of the protocol type.

The definition of DLT_AX25 already exists (protocol 3).
The attached patch adds recognition for the Amateur Radio AX.25 protocol

the ax.25 support was taken out.

I have also done some searching on the tcpdump mail-lists and not found
any references there of
