Detailed Description
UIP has a few global variables that are used in device drivers for UIP.
Variable Documentation
| u16_t uip_len |
The length of the packet in the uip_buf buffer.
The global variable uip_len holds the length of the packet in the uip_buf buffer.
When the network device driver calls the UIP input function, uip_len should be set to the length of the packet in the uip_buf buffer.
When sending packets, the device driver should use the contents of the uip_len variable to determine the length of the outgoing packet.
