interop tests show it did fix it :)
One issue is that the msgid is random, and if you stuff it in the
ike header using the struct, it is assumed host order and will be
flipped by out_struct()
The hash calculation therefor needs the flipped version to do its hash
I agree we could use a single function for this.
Note there is one case where this must not be done. I left a comment.
