Do you  mean commit 286446c1
https://git.kernel.org/pub/scm/network/iproute2/iproute2.git/commit/?id=286446c1e8c7f5f6eca4959015aa9e482b7adb11

Matt's patch is to support link.  
e.g ip link add ipsec0 type xfrm dev enp0s5 if_id 0xAB

Eyal's patch for xfrm state and policy.
e.g 
ip xfrm policy add src 10.1.1.200/32 dst 10.1.1.100/32 dir in tmpl src 
172.16.1.200 dst 172.16.1.100 proto esp reqid 2 mode tunnel if_id 10

Thanks for applying Matt's patch. We need for both patches.
