What about the decap-dscp ip xfrm flag?
I just pushed a patch to support decap-dscp. This will be released with
version 3.23 (and will appear in a pre-release when we do 3.23rc2)
Or you can apply the patch yourself:

I have not tested this other then confirming the flag shows up in the
output of "ip xfrm state".
