FUTURE

  * TODO: The lwIP source code makes some invalid assumptions on processor
    word-length, storage sizes and alignment. See the mailing lists for
    problems with exoteric (/DSP) architectures showing these problems.
    We still have to fix some of these issues neatly.

  * TODO: the PPP code is broken in a few ways. There are namespace
    collisions on BSD systems and many assumptions on word-length
    (sizeof(int)). In ppp.c an assumption is made on the availability of
    a thread subsystem. Either PPP needs to be moved to contrib/ports/???
    or rearranged to be more generic.

(STABLE-1.3.1)

  ++ New features:

  2009-05-10 Simon Goldschmidt
  * opt.h, sockets.c, pbuf.c, netbuf.h, pbuf.h: task #7013: Added option
    LWIP_NETIF_TX_SINGLE_PBUF to try to create transmit packets from only
    one pbuf to help MACs that don't support scatter-gather DMA.

  2009-05-09 Simon Goldschmidt
  * icmp.h, icmp.c: Shrinked ICMP code, added option to NOT check icoming
    ECHO pbuf for size (just use it): LWIP_ICMP_ECHO_CHECK_INPUT_PBUF_LEN

  2009-05-05 Simon Goldschmidt, Jakob Stoklund Olesen
  * ip.h, ip.c: Added ip_current_netif() & ip_current_header() to receive
    extended info about the currently received packet.

  2009-04-27 Simon Goldschmidt
  * sys.h: Made SYS_LIGHTWEIGHT_PROT and sys_now() work with NO_SYS=1

  2009-04-25 Simon Goldschmidt
  * mem.c, opt.h: Added option MEM_USE_POOLS_TRY_BIGGER_POOL to try the next
    bigger malloc pool if one is empty (only usable with MEM_USE_POOLS).

  2009-04-21 Simon Goldschmidt
  * dns.c, init.c, dns.h, opt.h: task #7507, patch #6786: DNS supports static
    hosts table. New configuration options DNS_LOCAL_HOSTLIST and
    DNS_LOCAL_HOSTLIST_IS_DYNAMIC. Also, DNS_LOOKUP_LOCAL_EXTERN() can be defined
    as an external function for lookup.

  2009-04-15 Simon Goldschmidt
  * dhcp.c: patch #6763: Global DHCP XID can be redefined to something more unique

  2009-03-31 Kieran Mansley
  * tcp.c, tcp_out.c, tcp_in.c, sys.h, tcp.h, opts.h: add support for
    TCP timestamp options, off by default.  Rework tcp_enqueue() to
    take option flags rather than specified option data

  2009-02-18 Simon Goldschmidt
  * cc.h: Added printf formatter for size_t: SZT_F

  2009-02-16 Simon Goldschmidt (patch by Rishi Khan)
  * icmp.c, opt.h: patch #6539: (configurable) response to broadcast- and multicast
    pings

  2009-02-12 Simon Goldschmidt
  * init.h: Added LWIP_VERSION to get the current version of the stack

  2009-02-11 Simon Goldschmidt (suggested by Gottfried Spitaler)
  * opt.h, memp.h/.c: added MEMP_MEM_MALLOC to use mem_malloc/mem_free instead
    of the pool allocator (can save code size with MEM_LIBC_MALLOC if libc-malloc
    is otherwise used)

  2009-01-28 Jonathan Larmour (suggested by Bill Bauerbach)
  * ipv4/inet_chksum.c, ipv4/lwip/inet_chksum.h: inet_chksum_pseudo_partial()
  is only used by UDPLITE at present, so conditionalise it.

  2008-12-03 Simon Goldschmidt (base on patch from Luca Ceresoli)
  * autoip.c: checked in (slightly modified) patch #6683: Customizable AUTOIP
    "seed" address. This should reduce AUTOIP conflicts if
    LWIP_AUTOIP_CREATE_SEED_ADDR is overridden.

  2008-10-02 Jonathan Larmour and Rishi Khan
  * sockets.c (lwip_accept): Return EWOULDBLOCK if would block on non-blocking
    socket.

  2008-06-30 Simon Goldschmidt
  * mem.c, opt.h, stats.h: fixed bug #21433: Calling mem_free/pbuf_free from
    interrupt context isn't safe: LWIP_ALLOW_MEM_FREE_FROM_OTHER_CONTEXT allows
    mem_free to run between mem_malloc iterations. Added illegal counter for
    mem stats.

  2008-06-27 Simon Goldschmidt
  * stats.h/.c, some other files: patch #6483: stats module improvement:
    Added defines to display each module's statistic individually, added stats
    defines for MEM, MEMP and SYS modules, removed (unused) rexmit counter.

  2008-06-17 Simon Goldschmidt
  * err.h: patch #6459: Made err_t overridable to use a more efficient type
    (define LWIP_ERR_T in cc.h)

  2008-06-17 Simon Goldschmidt
  * slipif.c: patch #6480: Added a configuration option for slipif for symmetry
    to loopif

  2008-06-17 Simon Goldschmidt (patch by Luca Ceresoli)
  * netif.c, loopif.c, ip.c, netif.h, loopif.h, opt.h: Checked in slightly
    modified version of patch # 6370: Moved loopif code to netif.c so that
    loopback traffic is supported on all netifs (all local IPs).
    Added option to limit loopback packets for each netifs.
