When compiling with gcc -O1, this error appears: drivers/net/mlx4/mlx4_ethdev.c: In function ‘mlx4_rxmode_toggle’: rte_log.h:321:3: error: ‘mode’ may be used uninitialized in this function The function mlx4_rxmode_toggle is never called with a value which is not in the switch block, but GCC complains about it with -O1. So the default case is "fixed" by setting string "undefined".
