Sorry, I missed you in my email on this patch set as I didn't realize
that the maintainers are different than the netdev maintainers. My bad.
The PRP driver support in kernel is merged by Dave to net-next and this
iproute2 change has to go with it. So please review and apply this if it
looks good. The kernel part merged is at

[net-next iproute2 PATCH v3 1/2] iplink: hsr: add support for creating PRP device similar to HSR
This patch enhances the iplink command to add a proto parameters to
create PRP device/interface similar to HSR. Both protocols are
quite similar and requires a pair of Ethernet interfaces. So re-use
the existing HSR iplink command to create PRP device/interface as
well. Use proto parameter to differentiate the two protocols.
