- * 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.

HISTORY
(CVS HEAD)
* [Enter new changes just after this line - do not remove this line]
+ ++ New features:
+
+ 2012-03-25: Simon Goldschmidt (idea by Mason)
+ * posix/*: added posix-compatibility include files posix/netdb.h and posix/sys/socket.h
+ which are a simple wrapper to the correct lwIP include files.
+
+ 2012-01-16: Simon Goldschmidt
+ * opt.h, icmp.c: Added option CHECKSUM_GEN_ICMP
+
+ 2011-12-17: Simon Goldschmidt
+ * ip.h: implemented API functions to access so_options of IP pcbs (UDP, TCP, RAW)
+ (fixes bug #35061)
+
+ 2011-09-27: Simon Goldschmidt
+ * opt.h, tcp.c, tcp_in.c: Implemented limiting data on ooseq queue (task #9989)
+ (define TCP_OOSEQ_MAX_BYTES / TCP_OOSEQ_MAX_PBUFS in lwipopts.h)
+
+ 2011-09-21: Simon Goldschmidt
+ * opt.h, api.h, api_lib.c, api_msg.h/.c, sockets.c: Implemented timeout on
+ send (TCP only, bug #33820)
+
+ 2011-09-21: Simon Goldschmidt
+ * init.c: Converted runtime-sanity-checks into compile-time checks that can
+ be disabled (since runtime checks can often not be seen on embedded targets)
+
+ 2011-09-11: Simon Goldschmidt
+ * ppp.h, ppp_impl.h: splitted ppp.h to an internal and external header file
+ to get a clear separation of which functions an application or port may use
+ (task #11281)
+
+ 2011-09-11: Simon Goldschmidt
+ * opt.h, tcp_impl.h, tcp.c, udp.h/.c: Added a config option to randomize
+ initial local TCP/UDP ports (so that different port ranges are used after
+ a reboot; bug #33818; this one added tcp_init/udp_init functions again)
+
+ 2011-09-03: Simon Goldschmidt
+ * dhcp.c: DHCP uses LWIP_RAND() for xid's (bug #30302)
+
+ 2011-08-24: Simon Goldschmidt
+ * opt.h, netif.h/.c: added netif remove callback (bug #32397)
+
+ 2011-07-26: Simon Goldschmidt
+ * etharp.c: ETHARP_SUPPORT_VLAN: add support for an external VLAN filter
+ function instead of only checking for one VLAN (define ETHARP_VLAN_CHECK_FN)
+
+ 2011-07-21: Simon Goldschmidt (patch by hanhui)
+ * ip4.c, etharp.c, pbuf.h: bug #33634 ip_forward() have a faulty behaviour:
+ Added pbuf flags to mark incoming packets as link-layer broadcast/multicast.
+ Also added code to allow ip_forward() to forward non-broadcast packets to
+ the input netif (set IP_FORWARD_ALLOW_TX_ON_RX_NETIF==1).
+
+ 2011-07-21: Simon Goldschmidt
+ * sockets.c, opt.h: (bug #30185): added LWIP_FIONREAD_LINUXMODE that makes
+ ioctl/FIONREAD return the size of the next pending datagram.
+
+ 2011-06-26: Simon Goldschmidt (patch by Cameron Gutman)
+ * tcp.c, tcp_out.c: bug #33604: added some more asserts to check that
+ pcb->state != LISTEN
+
+ 2011-05-25: Simon Goldschmidt
+ * again nearly the whole stack, renamed ip.c to ip4.c, ip_addr.c to ip4_addr.c,
+ combined ipv4/ipv6 inet_chksum.c, added ip.h, ip_addr.h: Combined IPv4
+ and IPv6 code where possible, added defines to access IPv4/IPv6 in non-IP
+ code so that the code is more readable.
+
+ 2011-05-17: Patch by Ivan Delamer (only checked in by Simon Goldschmidt)
+ * nearly the whole stack: Finally, we got decent IPv6 support, big thanks to
+ Ivan! (this is work in progress: we're just post release anyway :-)

+
2011-03-13: Simon Goldschmidt
* sockets.c: fixed bug #32769 (ESHUTDOWN is linux-specific) by fixing
err_to_errno_table (ERR_CLSD: ENOTCONN instead of ESHUTDOWN), ERR_ISCONN:
