Have you taken a look at rawshark, which comes with Wireshark?  I've 
never worked with it, but figured that I would let you know it exists in 
case it could be helpful.  From rawshark.c:

/*
 * Rawshark does the following:
 * - Opens a specified file or named pipe
 * - Applies a specfied DLT or "decode as" encapsulation
 * - Reads frames prepended with a libpcap packet header.
 * - Prints a status line, followed by fields from a specified list.
