Hi Wiresharkers,

I would like to throw out this suggestion as a possibly useful feature
that I suspect for a developer up-to-speed with the development
environment quite easily add.

As per "pcap-bpf.h", DLT_PPP (9) is supported to allow analysis fo PPP
packets.  However, for debugging a PPP session it would be useful to
display the direction the packet is travelling as well.

DLT_PPP_PPPD (166) is defined in "pcap-bpf.h" but not a type supported
by Wireshark.  The difference is simply an extra byte preceeds the
actual PPP packet containing 00 or 01 to indicate direction.

If someone was inspired to add this protocol type it could be quite
helpful for debugging PPP connection.

Thanks for your consideration

Kind regards
Dave
