This recipe includes the patches required in iproute2 to add
PRP ip link support as well as allow use of VLAN for supervision
frames.

+Subject: [PATCH 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.

+This patch adds support to configure vlan tag information

+Supervision frames. This is done by adding 3 additional attributes

+device through the ip link command.
