+Date: Tue, 25 Mar 2025 13:54:24 +0200
+Subject: [PATCH] lib: Return duplicate prefix-list entry test
+
+If we do e.g.:
+
+ip prefix-list PL_LoopbackV4 permit 10.1.0.32/32
+ip prefix-list PL_LoopbackV4 permit 10.1.0.32/32
+ip prefix-list PL_LoopbackV4 permit 10.1.0.32/32
+
+We end up, having duplicate records with a different sequence number only.
