be used uninitialized [-Wmaybe-uninitialized]
   40 |     __error_noreturn (__status, __errnum, __format,
   __va_arg_pack ());
         |
	 ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
	 udpgso_bench_rx.c: In function ‘main’:
	 udpgso_bench_rx.c:253:23: note: ‘gso_size’ was declared here
	   253 |         int ret, len, gso_size, budget = 256;
