-	 * Temporarily releasing the lock should be harmless for non-Linux TIPC,

+	 * networking mode as it calls tipc_eth_media_start(), which may sleep.
+	 * Releasing the lock is harmless as other locally-issued configuration
+	 * commands won't occur until this one completes, and remotely-issued
+	 * configuration commands can't be received until a local configuration
+	 * command to enable the first bearer is received and processed.
