+Subject: net: make sure we never create ifindex = 0
+
+From: Jakub Kicinski <kuba@kernel.org>
+
+commit ceaac91dcd065db781d1ed5dfaef0686b8ec44dc upstream.
+
+Instead of allocating from 1 use proper xa_init flag,
+to protect ourselves from IDs wrapping back to 0.
+
+Fixes: 759ab1edb56c ("net: store netdevs in an xarray")
