Hello, I'm aware this is a corner case that usually should not happen in a properly configured WPAN, but what is an implementation of selective fragment recovery supposed to do, if hop-limit 0 is reached? With minimal forwarding I just reassembled it and handed it to IPv6 so it can send a ICMPv6 Time exceeded error message. Should selective fragment recovery send an abort ACK in that case as well? Or just the abort ACK?
Best regards, Martine
