1574 by err_t type. Add a new err_t code "ERR_INPROGRESS".
1581 * netdb.c: add a LWIP_DNS_API_HOSTENT_STORAGE option to decide to use a static
1582 set of variables (=0) or a local one (=1). In this last case, your port should
1583 provide a function "struct hostent* sys_thread_hostent( struct hostent* h)"
1584 which have to do a copy of "h" and return a pointer ont the "per-thread" copy.

1704 call to a lower frequency). Or, you can decide to not call snmp_inc_sysuptime()
1708 when it's queried (any direct call to "sysuptime" is changed by a call to
1713 and others without it, there is a new NETIF_FLAG_IGMP flag to set in netif->flags
1720 * sockets.c, ip.h, api.h, tcp.h: declare a "struct ip_pcb" which only contains
1721 IP_PCB. Add in the netconn's "pcb" union a "struct ip_pcb *ip;" (no size change).
1735 parameters have to be provided: a task name, and a task stack size. For this
1747 memp_malloc, and use a new MEMP_NUM_IGMP_GROUP option (see opt.h to define the
1748 value). It will avoid potential fragmentation problems, use a counter to know
1749 how many times a group is used on an netif, and free it when all applications
1750 leave it. MEMP_NUM_IGMP_GROUP got 8 as default value (and init.c got a sanity
1758 The igmp_join/leavegroup first parameter change from a netif to an ipaddr.
1759 This field could be a netif's ipaddr, or "any" (same meaning than ip_addr_isany).

1779 a place to add code for task #7142 "Sanity check user-configurable values".
1793 Add a netif_is_link_up() function if LWIP_NETIF_LINK_CALLBACK option is set.
1834 * ethernetif.c, contrib/ports/various: ethbroadcast now a shared global
1853 a link callback in the netif struct, and functions to handle it. Be carefull
1866 MEM_USE_POOLS to use 4 pools with different sized elements instead of a
1867 heap. This both prevents memory fragmentation and gives a higher speed
1873 int to be able to send a bigger buffer than 64K with one time (mainly
1878 into a define (tcp_output_nagle) in tcp.h to provide it to raw api users, too.
1886 * etharp.c, etharp.h: Changed etharp to use a defined hardware address length
1888 used for ethernet and struct eth_addr already had a defined length of 6).

2147 allocate a recvmbox in netconn_new_with_proto_and_callback. For a tcp-listen
2148 netconn, this recvmbox is later freed and a new mbox is allocated for acceptmbox.
2149 This is a fix for thread-safety and allocates all items needed for a netconn

2336 a "pseudo-random" value based on netif's MAC and some autoip fields. It's always

2509 the mailbox is active". Now, the post is only done during a connect, and do_send,
2510 do_write and do_join_leave_group don't do anything if a previous error was signaled.
2517 * api_msg.c: add a "pcb_new" helper function to avoid redundant code, and to add
2526 result and can cause a crash. lwip_send now check netbuf_ref result.
2539 * api_lib.c: patch for netconn_write(), fixes a possible race condition which cause
2540 to send some garbage. It is not a definitive solution, but the patch does solve
2552 it's a good idea to upgrade them, even if before, there could be another problem
2556 * sockets.c: fixed bug #5067 (essentialy a signed/unsigned warning fixed
2561 api_lib.c to tcpip.c's tcpip_apimsg(). Now, use a local variable and not a
2562 dynamic one from memp to send tcpip_msg to tcpip_thread in a synchrone call.

3033 Use PBUF_REF to make a pbuf refer to RAM. lwIP will use zero-copy
3035 a copy-on-demand when necessary.
3049 * IP_ADDR_ANY is no longer a NULL pointer. Instead, it is a pointer
3050 to a '0.0.0.0' IP address.
