Subject: What is the "ll header" of a PPP Interface?

Hi,

I occasionally get syslog messages about "martians" coming in on a PPP interface.
Normally, the reported ll header is the 2 involved MAC addresses and the ethernet
frame type. For the PPP interface however, the reported ll header is 22 bytes long
and I can't find any information about the significance of it.

Can somebody here maybe enlighten me?

Regards,
                         Peter
