[Snort-users] Linktype 113 not decoded

I'm running into an issue I hope someone can help with.

Environment:
Snort-2.3.0
Barnyard-0.2.0
Libpcap-0.7.2-7.E3.2
RedHat ES 3 update 3 SMP (2.4.21-20.Elsmp)

The system is running 2 GigE fibre cards that are spanning 2 routers
with no ip address and snort starts with -i any.  The problem is the
alerts have no ip/tcp/udp header information.  Looking at barnyards
dump.log I'm getting "Linktype 113 not decoded.  Raw packet dumped"
instead of the packet header.  If I run tcpdump or ethereal on any of
the interfaces, I am able to get all header info.

Any help would be greatly appreciated.

Bill
