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.

Just wondering who will merge this now that PRP support series below
is applied to net-next. These iproute2 patches have to go along with 
that to have full PRP support working.

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

there was a long delay between iproute2 and commit to net-next. You need
to re-send the iproute2 patches.
