I was able to successfully do MPLS/GRE (without TEB, ie. 
options:packet_type=legacy_l3) with this patch series, on a 4.11 kernel 
with the openvswitch kernel module provided with OVS (DKMS compiled), 
and with the kernel openvswitch module as well.

It is really great to this this work today!

However, as per our discussion on irc yesterday [1], I wasn't able to 
have this working (issue on reception) on an 4.8.x kernel, even with the 
openvswitch kernel module provided with OVS. Is it possible that another 
kernel fix/modification is needed that is not in 4.8.x ?
