I am working on this helper function and will send RFC shortly.
FWIW, ixgbe probably won't use the IPv6 extension header check, because I am working on simply adding offload support for it. It seems to me that if segment routing becomes used, in some places there will be enough traffic with it present to want it offloaded. Well, maybe ixgbe should use the extension header check until I get the offload support done, but that is it. Are there any good tools for testing IPv6 extension headers? It seems that it hasn't been tested up to this point or the ixgbe problem would have been noticed, so it would be good to introduce a good tool to test it properly. -- Mark Rustad, Networking Division, Intel Corporation
