+Subject: [PATCH] backports: only add net_get_random_once() when not available
+
+Upstream commit: d787b3dd3b4fcb5f40eb6532163dc3abdca4fd45
+
+net_get_random_once() was added unconditionally also when the kernel we
+are compiling against already provided this function, this patch checks
+that first.
