Ping IP address asignment.

uIP uses a "ping" packets for setting its own IP address if this option is set. If so, uIP will start with an empty IP address and the destination IP address of the first incoming "ping" (ICMP echo) packet will be used for setting the hosts IP address.<p>

Turn on support for IP packet reassembly. 
<p>
uIP supports reassembly of fragmented IP packets. This features requires an additonal amount of RAM to hold the reassembly buffer and the reassembly code size is approximately 700 bytes. The reassembly buffer is of the same size as the uip_buf buffer (configured by UIP_BUFSIZE).<p>
<dl compact><dt><b>Note:</b></dt><dd>IP packet reassembly is not heavily tested. </dd></dl>
