commit bbc5882fb9ac4b1a9815c9c634d977e8776d73fa
Author: Tom Rondeau <address@hidden>
Date:   Fri May 16 15:56:55 2014 -0400

    digital: don't need the FEC info for the tagged stream corr access code.
    
    Currently, running FEC on payload before header, so the header encodes the 
fully encoded payload lenth.
