+Subject: [PATCH] addons: vxlan: fix VNI filter on single VXLAN device
+
+In af8d5db22b10909ff06032f1a2acc2f745d1f65b, the transformation of
+`vnis` (list) to `vnisd` (dictionary) left a reference to `vnis` which
+is now undefined. We just remove the line as the conversion from range
+to ints is done earlier in the function.
