Subject: [PATCH net v4 1/4] selftests: net: udpgso_bench_rx: Fix 'used uninitialized' compiler warning
Date: Wed,  1 Feb 2023 00:16:10 +0000	[thread overview]
Message-ID: <20230201001612.515730-1-andrei.gherzan@canonical.com> (raw)

This change fixes the following compiler warning:

/usr/include/x86_64-linux-gnu/bits/error.h:40:5: warning: ‘gso_size’ may
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;
