Unfortunately, tag_brcm.c, for example, doesn't give *enough* details - it has a bunch of uncommented #defines (some of 
which suggest overlap between fields in the same byte of the tag) and some code that doesn't handle all the fields in 
both ingress and egress tags.

Can you construct "ASCII-art" diagrams and explanatory text, of the sort seen in, for example:

        http://www.tcpdump.org/linktypes/LINKTYPE_LINUX_SLL.html

for the tags?
