Hi, I've been reading through the implementation code of IPv6 and specifically ip6_input. I see the following. IPv6 uses the same protocol switch to process both the protocols (like = UDP & TCP) and also the option headers like Fragmentation. My question is: Are these numbers are promised to be aligned even in the future? = Basically if a protocol number will be the same as an option number this will not work. The same question applies to IPv4 (even though your implementation is = not using this trick there). Can we safely process IPv4 options the same = way?
