/* psock Protosockets library
*
* The protosocket library provides an interface to the uIP stack that is
* similar to the traditional BSD socket interface. Unlike programs
* written for the ordinary uIP event-driven interface, programs
* written with the protosocket library are executed in a sequential
* fashion and does not have to be implemented as explicit state
* machines.
*
* Protosockets only work with TCP connections.
*
* The protosocket library uses \ref pt protothreads to provide
* sequential control flow. This makes the protosockets lightweight in
* terms of memory, but also means that protosockets inherits the
* functional limitations of protothreads. Each protosocket lives only
* within a single function. Automatic variables (stack variables) are
* not retained across a protosocket library function call.
*
* \note Because the protosocket library uses protothreads, local
* variables will not always be saved across a call to a protosocket
* library function. It is therefore advised that local variables are
* used with extreme care.
*
* The protosocket library provides functions for sending data without
* having to deal with retransmissions and acknowledgements, as well
* as functions for reading data without having to deal with data
* being split across more than one TCP segment.
*
* Because each protosocket runs as a protothread, the protosocket has to be
* started with a call to PSOCK_BEGIN() at the start of the function
* in which the protosocket is used. Similarly, the protosocket protothread can
* be terminated by a call to PSOCK_EXIT().

* in the uip_buf packet buffer. If so, the uip_len variable is set to
* the length of the packet. If no packet is to be sent out, the

*

* Implementation of the ARP Address Resolution Protocol.
* Author: Adam Dunkels <adam@dunkels.com>
*
* The Address Resolution Protocol ARP is used for mapping between IP
* addresses and link level addresses such as the Ethernet MAC
* addresses. ARP uses broadcast queries to ask for the link level
* address of a known IP address and the host which is configured with
* the IP address for which the query was meant, will respond with its
* link level address.
*
* Note: This ARP implementation only supports Ethernet.

/**
* \defgroup uipsplit uIP TCP throughput booster hack
* @{
*
* The basic uIP TCP implementation only allows each TCP connection to
* have a single TCP segment in flight at any given time. Because of
* the delayed ACK algorithm employed by most TCP receivers, uIP's
* limit on the amount of in-flight TCP segments seriously reduces the
* maximum achievable throughput for sending data from uIP.
*
* The uip-split module is a hack which tries to remedy this
* situation. By splitting maximum sized outgoing TCP segments into
* two, the delayed ACK algorithm is not invoked at TCP
* receivers. This improves the throughput when sending data from uIP
* by orders of magnitude.
*
* The uip-split module uses the uip-fw module (uIP IP packet
* forwarding) for sending packets. Therefore, the uip-fw module must
* be set up with the appropriate network interfaces for this module
* to work.

/* uip-resolv.c
* DNS host name to IP address resolver.
* Author: Adam Dunkels <adam@dunkels.com>
*
* The uIP DNS resolver functions are used to lookup a hostname and
* map it to a numerical IP address. It maintains a list of resolved
* hostnames that can be queried with the resolv_lookup()
* function. New hostnames can be resolved using the resolv_query()
* function.
*
* When a hostname has been resolved (or found to be non-existant),
* the resolver code calls a callback function called resolv_found()
* that must be implemented by the module that uses the resolver.
