ipv4: Initialize on-stack cork more efficiently.
ip_setup_cork() explicitly initializes every member of inet_cork except flags, addr, and opt. So we can simply set those three members to zero instead of using a memset() via an empty struct assignment. Signed-off-by: David S. Miller <davem@davemloft.net> Acked-by: Eric Dumazet <eric.dumazet@gmail.com>
