fix printing of recved packet.Discovered by Ed Sutter

with an equivalent pbuf_alloc.When we know we'll have to adjust the payload for the TCP header
just alloc it like that from the start.

+lwIP is a small independent implementation of the TCP/IP protocol
+suite that has been developed by Adam Dunkels at the Computer and
+Networks Architectures (CNA) lab at the Swedish Institute of Computer
+Science (SICS).
+
+The focus of the lwIP TCP/IP implementation is to reduce the RAM usage
+while still having a full scale TCP. This making lwIP suitable for use
+in embedded systems with tenths of kilobytes of free RAM and room for
+around 40 kilobytes of code ROM.
+
+lwIP features:
+ * IP (Internet Protocol) including packet forwarding over multiple
+   network interfaces
+ * ICMP (Internet Control Message Protocol) for network maintenance
+   and debugging
+ * UDP (User Datagram Protocol) including experimental UDP-lite
+   extensions
+ * TCP (Transmission Control Protocol) with congestion control, RTT
+   estimation and fast recovery/fast retransmit
+ * Specialized API for enhanced performance
+ * Optional Berkeley socket API
+
+lwIP is freely available under a BSD license.
+
+lwIP has grown into an excellent TCP/IP stack for embedded devices,
+and developers using the stack often submit bug fixes, improvements,
+and additions to the stack to further increase its usefulness.
+
+Development of lwIP is hosted on Savannah, a central point for
+software development, maintenance and distribution. A core team
+will improve lwIP by the use of Savannah's interface and CVS.
+
+The current lwIP CVS tree can be checked out by doing:
+  cvs -d:pserver:anoncvs@subversions.gnu.org:/cvsroot/lwip login
+  cvs -z3 -d:pserver:anoncvs@subversions.gnu.org:/cvsroot/lwip co lwip
+
+Last night's CVS tar ball can be downloaded from:
+  http://savannah.gnu.org/cvs.backups/lwip.tar.gz
+
+The current CVS tree is web-browsable:
+http://savannah.nongnu.org/cgi-bin/viewcvs/lwip/lwip/
+
+Submit patches and bugs via the lwIP project page:
+  http://savannah.nongnu.org/projects/lwip/
+
+Stable releases have not been released yet. For development we
+suggest downloading the latest CVS and keeping track of the
+lwIP mailing list.
+
+The mailing list (with searchable archives), as well as Adam
+Dunkels' papers on lwIP are at the official lwIP home page:
+  http://www.sics.se/~adam/lwip/
+
+Reading Adam's papers and browsing the mailing list archives
+is a good way to become familiar with the design of lwIP.

+lwIP for Win32
+
+***WARNING***
+The current CVS code of this port isn't much tested.
+***WARNING***
+
+This is a quickly hacked port and example project of the lwIP library to
+Win32/MSVC.
+
+Due to the nature of the lwip library you have to copy this whole project
+into a new subdir in proj and modify lwipopts.h to your needs. If you move
+it to another directory besides proj, you have to update the include paths
+in the project settings.
+
+Included in the proj/msvc6 directory is the network interface driver using
+the winpcap library.
+
+There is no more documentation yet. Try to figure it out yourself.
+
+This is provided as is, it's just a hack to test some stuff, no serious
+implementation.

+This directory contains an example of how to compile lwIP as a self
+initialising shared library on Linux.
+
+Some brief instructions:
+ 
+* Compile the code:
+
+ > make clean all
+
+ This should produce liblwip4unixlib.so.  This is the shared library.
+
+* Link an application against the shared library
+
+ If you're using gcc you can do this by including -llwip4unixlib in
+your link command. 
+
+* Run your application
+ 
+ Ensure that LD_LIBRARY_PATH includes the directory that contains
+liblwip4unixlib.so (ie. this directory)
+
+
+
+If you are unsure about shared libraries and libraries on linux in
+general, you might find this HOWTO useful:

+	    The web page you are watching was served by a simple web
+	    server running on top of the lightweight TCP/IP stack <a
+	    href="http://www.sics.se/~adam/lwip/">lwIP</a>.
+	  </p>
+	  <p>
+	    lwIP is an open source implementation of the TCP/IP
+	    protocol suite that was originally written by Adam Dunkels
+	    of the Swedish Institute of Computer Science but now is
+	    being actively developed by a team of developers
+	    distributed world-wide. Since it's release, lwIP has
+	    spurred a lot of interest and has been ported to several
+	    platforms and operating systems. lwIP can be used either
+	    with or without an underlying OS.
+	  </p>
+	  <p>
+	    The focus of the lwIP TCP/IP implementation is to reduce
+	    the RAM usage while still having a full scale TCP. This
+	    makes lwIP suitable for use in embedded systems with tens
+	    of kilobytes of free RAM and room for around 40 kilobytes
+	    of code ROM.
+	  </p>
+	  <p>
+	    More information about lwIP can be found at the lwIP
+	    homepage at <a
+	    href="http://www.sics.se/~adam/lwip/">http://www.sics.se/~adam/lwip/</a>.

-<h2>Using lwIP with or without an operating system</h2>
-
-<p align="justify">
-There has been a few questions about how lwIP can be used in a
-standalone environment (i.e., an environment without a multi-threaded
-operating system) lately. The purpose of this document is to describe
-how lwIP is designed to be used with and without a multi-threaded
-operating system.
-</p>
-
-<center><img src="os.png"></center>
-
-<h3>The lwIP single-threaded core</h3>
-<p align="justify">
-The core of lwIP consists of the actual implementations of the IP,
-ICMP, UDP, and TCP protocols, as well as the support functions such as
-buffer and memory management. The core components are the only ones
-that are needed when lwIP is to be run in a single-threaded (non-OS)
-environment. 
-</p>
-<p align="justify">
-The core components can be viewed as a software library which has the
-following interface:
-</p>
-<ul>
-<li><tt>ip_input(pbuf, netif)</tt>: Takes an IP packet and the incoming network
-interface as arguments and does the TCP/IP processing for the packet.
-<li><tt>tcp_tmr()</tt>: Should be called every 100 ms. Does all TCP
-timer processing such as doing retransmissions.
-</ul>
-<p align="justify">
-Because none of the core functions ever needs to block when run in a
-single-threaded environment, the <tt>sys_arch</tt> (the operating
-system abstraction layer) does not need to implement locking
-semaphores or mailboxes. In future versions of lwIP, the dependancy of
-the <tt>sys_arch</tt> will be removed in the single-threaded case.
-</p>
-<p align="justify">
-A simple main loop for a single-threaded system might look
-like this:
-</p>
-<pre>
-  while(1) {
-    if(poll_driver(netif) == PACKET_READY) {
-      pbuf = get_packet(netif);
-      ip_input(pbuf, netif);
-    }
-
-    if(clock() - last_time == 100 * CLOCK_MS) {
-      tcp_tmr();
-      last_time = clock();
-    }    
-  }
-</pre>
-
-<h3>lwIP in a multi-threaded system</h3>
-<p align="justify">
-lwIP is designed to be able to be run in a multi-threaded system with
-applications running in concurrent threads. The model used in this
-case is that all TCP/IP processing is done in a single thread. The
-application thread communicate with the TCP/IP thread using the
-sequential API.
-</p>
-
-<center><img src="threads.png"></center>
-
-<p align="justify">
-The inter-thread communication is implemented in the two files
-<tt>api_lib.c</tt> and <tt>api_msg.c</tt>. The former contains the
-functions used by the application programs and the latter implements
-the TCP/IP stack interface. A third file, <tt>tcpip.c</tt>, handles
-incoming packets and timer events as described in the previous
-section. 
-</p>
-
-<p align="justify">
-When run in a multi-threaded environment, incoming packets are handled
-by the function <tt>tcpip_input()</tt>, which takes the same arguments
-as the <tt>ip_input()</tt> function. The difference between the two
-functions is that the <tt>tcpip_input()</tt> function does not process
-the incoming packet immediately. It merely puts the packet on a queue
-which later is drained by the TCP/IP thread.
-</p>
-
-<p align="justify">
-When being run in a multi-threaded system, timer events are taken care
-of internally in <tt>tcpip.c</tt>.
-</p>

+This directory contains architecture and compiler specific stuff for porting lwIP

+The sequential API has not been ported; it's function are empties. If someone is

+
+Besides this, a Cirrus (formerly Crystal Semiconductors) CS8900a Ethernet driver

+ *
+ * This is a device driver for the Crystal Semiconductor CS8900
+ * chip in combination with the lwIP stack.
+ *
+ * This is work under development. Please coordinate changes
+ * and requests with Leon Woestenberg <leon.woestenberg@axon.tv>

+ * source code under any conditions they seem fit.
+ *
+ * A quick function roadmap:
+ *
+ * cs8900_*() are low level, cs8900 hardware specific functions.
+ * These are declared static in the device driver source and
+ * SHOULD NOT need to be called from outside this source.
+ *
+ * cs8900if_*() are the lwIP network interface functions.
+ * 
+ * cs8900_interrupt() is an early interrupt service routine (ISR).
+ * It merely sets a flag to indicate the cs8900 needs servicing.
+ * (This function MAY be tied to an interrupt vector, IF present).
+ *
+ * cs8900_service() is the actual interrupt event service routine.
+ * It must be called whenever the cs8900 needs servicing. It MAY
+ * be polled safely (so, you do NOT NEED interrupt support.)
+ *
+ * cs8900_init() sets up the cs8900, using its register set. When
+ * using the driver on your particular hardware platform, make sure
+ * the register setups match.
+ * Function is called from cs8900if_init().
+ *
+ * cs8900_input() transfers a received packet from the chip.
+ * Function is called from cs8900if_input().
+ *
+ * cs8900_output() transfers a packet to the chip for transmission.
+ * Function is called from cs8900if_output().
+ *
+ * cs8900if_init() initializes the lwIP network interface, and
+ * calls cs8900_init() to initialize the hardware.
+ * Function is called from lwIP.
+ * 
+ * cs8900if_service() is the service routine, which must be called
+ * upon the need for service, or on a regular basis, in order to
+ * service the Ethernet chip.
+ *
+ * cs8900if_input() calls cs8900_input() to get a received packet
+ * and then forwards the packet to protocol(s) handler(s).
+ * Function is called from cs8900_service().
+ *
+ * cs8900if_output() resolves the hardware address, then
+ * calls cs8900_output() to transfer the packet.
+ * Function is called from lwIP.
+ *
+ * Future development:
+ * 
+ * Split the generic Ethernet functionality (a lot of the
+ * cs8900if_*() functions) and the actual cs8900a dependencies.
+ *
+ * Enhance the interrupt handler to service the Ethernet
+ * chip (to decrease latency); support early packet
+ * inspection (during reception) to early drop unwanted
+ * packets, minimize chip buffer use and maximize throughput.
+ *
+ * Statistics gathering, currently under development.
+ * SNMP support, currently under development.
