// LWIP_NETCONN_SEM_PER_THREAD==1: Use one (thread-local) semaphore per

// ATTENTION: a thread-local semaphore for API calls is needed:
// - LWIP_NETCONN_THREAD_SEM_GET() returning a sys_sem_t*
// - LWIP_NETCONN_THREAD_SEM_ALLOC() creating the semaphore
// - LWIP_NETCONN_THREAD_SEM_FREE() freeing the semaphore
// The latter 2 can be invoked up by calling netconn_thread_init()/netconn_thread_cleanup().

LWIP V2.0.3， 以上是根据个人的理解，以及反复测试得出的配置，占用内存比较大，但数据速率可以到50Mbps以上，还比较稳定。
在IAR下，只能低优先级优化，不要开中、高优先级优化。工程由 CubeMX 自动生成。
