1539 in opt.h to indicate sizes for tcpip::mbox, netconn::recvmbox, and for the

1645 core header files in api.h (ip/tcp/udp/raw.h) to hide the internal
1650 RAW netconn. You need to set LWIP_SO_RCVBUF=1 in your lwipopts.h (it's disabled
1651 by default). Netconn API users can use the netconn_recv_bufsize macro to access
1652 it. This is a first release which have to be improve for TCP. Note it used the

2324 * tcp.h, tcp.c, tcp_in.c, tcp_out.c: Added some ASSERTS and casts to prevent
2325 warnings when assigning to smaller types.

2551 * ethernetif.c: update netif->input calls to check return value. In older ports,
2552 it's a good idea to upgrade them, even if before, there could be another problem
2553 (access to an uninitialized mailbox).

2573 * opt.h Change default PBUF_POOL_BUFSIZE to accomodate default MSS +
2577 * Fix all uses of pbuf_header to check the return value. In some

2626 * tcpip.c: Initialize dhcp timers in tcpip_thread (if LWIP_DHCP) to protect
2631 call to "lwip_stats.link.recv++;" in low_level_input() & ethernetif_input().
2640 Allow to do ARP processing for incoming packets inside tcpip_thread
2642 old code using tcp_input with new define ETHARP_TCPIP_INPUT set to 0.

2660 The api_msg struct stay on the stack (not moved to netconn struct).
2669 existing pbuf chain when enqueuing multiple pbufs to a pending ARP request
2676 * tcpip.c: Moved call to ip_init(), udp_init() and tcp_init() from
2677 tcpip_thread() to tcpip_init(). This way, raw API connections can be

2842 * etharp.c: ETHARP_CREATE is renamed to ETHARP_TRY_HARD.
2843 Do not try hard to insert arbitrary packet's source address,
2848 * ipv4/ip_addr.h: Renamed ip_addr_maskcmp() to _netcmp() as we are
2852 IP address actually belongs to the network of the given interface.
2860 * tcp.c: Add code to tcp_recved() to send an ACK (window update) immediately,
2862 (currently TCP_WND/2). This avoids waiting for a timer to expire to send a
2863 delayed ACK in order to open the window if the stack is only receiving data.
2873 * debug.h: Added (int) cast in LWIP_DEBUGF() to avoid compiler
2880 * inet.c: Added a couple of casts to quiet the compiler.
