The IPV6 _EXT bits can come later.
Neither our driver independent soft-LRO nor any of the in-tree drivers can currently deal if extension headers and punt anything to software to my best knowledge; there is also very limited support for them in hardware anyway. I did started prototyping two different strategies for “library functions” that could be used in various places in the stack but never got to the point to properly evaluate them so far (and would probably have to find them on a turned off machine currently). But yes, ignoring them for now will be ok, and once we do them we need to do them everywhere in the stack anyway;-) — Bjoern A. Zeeb "Come on.
