[PATCH net 2/4] selftests/tcp_ao: Zero-init tcp_ao_info_opt

[Dmitry Safonov via B4 Relay]

From: Dmitry Safonov <0x7f454...@gmail.com>

The structure is on the stack and has to be zero-initialized as
the kernel checks for:
>       if (in.reserved != 0 || in.reserved2 != 0)
>               return -EINVAL;

Fixes: b26660531cf6 ("selftests/net: Add test for TCP-AO add setsockopt() 
command")
