/* Define the sys_mbox_set_invalid() to empty to support lock-free mbox in ESP LWIP.
*
* The basic idea about the lock-free mbox is that the mbox should always be valid unless
* no socket APIs are using the socket and the socket is closed. ESP LWIP achieves this by
* following two changes to official LWIP:
* 1. Postpone the deallocation of mbox to netconn_free(), in other words, free the mbox when
* no one is using the socket.
* 2. Define the sys_mbox_set_invalid() to empty if the mbox is not actually freed.
* The second change is necessary. Consider a common scenario: the application task calls
* recv() to receive packets from the socket, the sys_mbox_valid() returns true. Because there
* is no lock for the mbox, the LWIP CORE can call sys_mbox_set_invalid() to set the mbox at
* anytime and the thread-safe issue may happen.
*
* However, if the sys_mbox_set_invalid() is not called after sys_mbox_free(), e.g. in netconn_alloc(),
* we need to initialize the mbox to invalid explicitly since sys_mbox_set_invalid() now is empty.
