I'll try to make it, it's not so simple as I thought on the first
glance but some hack should be possible. Please note that this code 
will break the nice structure of unfolding encapsulation layers in
their natural order; it has to early analyze certain encapsulated 
data, skipping layer that actually should have been analyzed later!

As result, the memcopy range limiter code will bloat in the similar 
type of cumbersome code in the sections that we just recently got rid 
off.

(I wonder could we simplify crc troubles and just ignore crc)
