  To: meta-arago; +Cc: Hongmei Gou, Murali Karicheri

When ip -d link command is executed with prp interface setup,
it encounters a segmentation fault. This causes snmpwalk command
to time out since it uses the above command to list the
interfaces. This patch fixes the issue.

+Subject: [PATCH 1/2] hsr/prp: disable display for vlan params in ip -d link
+ command
+
+Seeing a crash with ip -d link command for prp. Disable it for now
+as a trial to check if that is causing the segmentation fault
+for prp. These values are not coming from kernel anyways. So it
+doesn't correctly display it currently. So this has no impact on
+the functionality. Can add it later once kernel provide the right
+values in the response.
