  * Event explanation:
- * 
+ *
  * In the netconn implementation, there are three ways to block a client:
- * 
+ *
  * - accept mbox (sys_arch_mbox_fetch(&conn->acceptmbox, &accept_ptr, 0); in netconn_accept())
  * - receive mbox (sys_arch_mbox_fetch(&conn->recvmbox, &buf, 0); in netconn_recv_data())
  * - send queue is full (sys_arch_sem_wait(LWIP_API_MSG_SEM(msg), 0); in lwip_netconn_do_write())
- * 
+ *
  * The events have to be seen as events signaling the state of these mboxes/semaphores. For non-blocking
  * connections, you need to know in advance whether a call to a netconn function call would block or not,
  * and these events tell you about that.
- * 
- * RCVPLUS events say: Safe to perform a potentially blocking call call once more. 
+ *
+ * RCVPLUS events say: Safe to perform a potentially blocking call call once more.
  * They are counted in sockets - three RCVPLUS events for accept mbox means you are safe
  * to call netconn_accept 3 times without being blocked.
  * Same thing for receive mbox.
- * 
+ *
  * RCVMINUS events say: Your call to to a possibly blocking function is "acknowledged".
  * Socket implementation decrements the counter.
- * 
+ *
  * For TX, there is no need to count, its merely a flag. SENDPLUS means you may send something.
  * SENDPLUS occurs when enough data was delivered to peer so netconn_send() can be called again.
  * A SENDMINUS event occurs when the next call to a netconn_send() would be blocking.
