/* The following flags may be set in the set of flags before calling the
* application callback. The UIP_ACKDATA, UIP_NEWDATA, and UIP_CLOSE flags
* may be set at the same time, whereas the others are mutually exclusive.
*
* UIP_ACKDATA IN: Signifies that the outstanding data was ACKed and
* the application should send out new data instead
* of retransmitting the last data (TCP only)
* OUT: Input state must be preserved on output.
* UIP_NEWDATA IN: Set to indicate that the peer has sent us new data.
* OUT: Cleared (only) by the application logic to indicate
* that the new data was consumed, suppressing further
* attempts to process the new data.
* UIP_SNDACK IN: Not used; always zero
* OUT: Set by the application if the new data was consumed
* and an ACK should be sent in the response. (TCP only)
* UIP_REXMIT IN: Tells the application to retransmit the data that
* was last sent. (TCP only)
* OUT: Not used
* UIP_POLL IN: Used for polling the application. This is provided
* periodically from the drivers to support (1) timed
* operations, and (2) to check if the application has
* data that it wants to send
* OUT: Not used
* UIP_BACKLOG IN: There is a new connection in the backlog list set
* up by the listen() command. (TCP only)
* OUT: Not used
* UIP_CLOSE IN: The remote host has closed the connection, thus the
* connection has gone away. (TCP only)
* OUT: The application signals that it wants to close the
* connection. (TCP only)
* UIP_ABORT IN: The remote host has aborted the connection, thus the
* connection has gone away. (TCP only)
* OUT: The application signals that it wants to abort the
* connection. (TCP only)
* UIP_CONNECTED IN: We have got a connection from a remote host and have
* set up a new connection for it, or an active connection
* has been successfully established. (TCP only)
* OUT: Not used
* UIP_TIMEDOUT IN: The connection has been aborted due to too many
* retransmissions. (TCP only)
* OUT: Not used
* UIP_ECHOREPLY IN: An ICMP Echo Reply has been received. Used to support
* ICMP ping from applications. (ICMP only)
* OUT: Cleared (only) by the application logic to indicate
* that the reply was processed, suppressing further
* attempts to process the reply.
