                 CHIP SDK performs LwIP core locking before calling an LwIP API.
                 To make the calls thread safe we have to enable LWIP_TCPIP_CORE_LOCKING.
+                Otherwise CHIP SDK will post LwIP APIs to TCPIP task to ensure thread safety.
                 Here, we are also enabling LWIP_CHECK_THREAD_SAFETY which will assert when
                 LwIP code gets called from any other context or without holding the LwIP lock.
