Yep, I have those moments.  Just when I think I've got git sussed it
goes and does something completely logical but totally unexpected :-)

Ah, so if I can work out how that's done I'm 50% of the way there. 
Should keep me amused for a few days.

Well here's interesting.  I got brave and put my suggested change into
action.  So far: 1) router not blown up  2) tc -s still shows traffic in
different Classes (Dave, I prefer your term 'Bin' here too - I
considered 'Bucket' for a laugh) which suggests the reading of ip_hdr is
still working. 3) This hasn't been thoroughly tested in any way
whatsoever but i've tried diffserv4 & besteffort and both don't appear
