What was the question, again?

The "[!] WARNING: Not IPv4 datagram!" deal?

You are capturing to file with tcpdump -w (what libpcap version?) and
reading the packet captures back through snort? (what snort version?).

When I replay the attachment you posted through snort 1.8.7 build 128,
it replays perfectly.
