+    ebtables: Fix corner-case noflush restore bug
+
+    Report came from firwalld, but this is actually rather hard to trigger.
+    Since a regular chain line prevents it, typical dump/restore use-cases
+    are unaffected.
+
+    Fixes: 73611d5582e72 ("ebtables-nft: add broute table emulation")
