-Subject: [PATCH] Change message type by dedicated function
-
-Long-term pointer to beginning of message does not work well. I case
-outpacket is reallocated in any new_opt6() section, original outmsgtypep
-pointer becomes invalid. Instead of using that pointer use dedicated
-function, which will change just the first byte of the message.
-
-This makes sure correct beginning of packet is always used.
