You might want to point out in the readme that DHCP can cause issues for a 450-byte packet size. The default DHCP Offer packet is 590 bytes. Some routers have a configuration to reduce it down to the ~300 necessary bytes, but others do not. (See http://www.linksysinfo.org/index.php?threads/dhcp-reduce-packet-size.20699/ for one example).
In fact, RFC2131 says, "A DHCP client must be prepared to receive DHCP messages with an 'options' field of at least length 312 octets. This requirement implies that a DHCP client must be prepared to receive a message of up to 576 octets, the minimum IP datagram size an IP host must be prepared to accept [3]. " No help to those of us on MCU's!
