Configuration file for MityDSP lwIP port.

Note:: Based upon opt.h as provided with lwIP.

Define Documentation

#define SUPPORT_VLAN_TAGGING 1

This is a MityDSP port specific option at LWIP 1.3.0.

#define VLAN_LINK_EXTEND 4

#define SYS_LIGHTWEIGHT_PROT 0

SYS_LIGHTWEIGHT_PROT==1: if you want inter-task protection for certain critical regions during buffer allocation, deallocation and memory allocation and deallocation.

#define MEM_LIBC_MALLOC 0

MEM_LIBC_MALLOC==1: Use malloc/free/realloc provided by your C-library instead of the lwip internal allocator. Can save code size if you already use it.

#define MEM_ALIGNMENT CACHE_L2_LINESIZE

#define ETH_PAD_SIZE 2

ETH_PAD_SIZE: Number of bytes required to align IP header (14 bytes) to the required byte boundary for this architecture.

Note:: This value cannot be changed without recompilation of the MityDSP Net library!

#define MEM_SIZE (64 * 1024)

MEM_SIZE: the size of the heap memory. If the application will send a lot of data that needs to be copied, this should be set high.

#define MEMP_OVERFLOW_CHECK 0

MEMP_OVERFLOW_CHECK: memp overflow protection reserves a configurable amount of bytes before and after each memp element in every pool and fills it with a prominent default value. MEMP_OVERFLOW_CHECK == 0 no checking MEMP_OVERFLOW_CHECK == 1 checks each element when it is freed MEMP_OVERFLOW_CHECK >= 2 checks each element in every pool every time memp_malloc() or memp_free() is called (useful but slow!)

#define MEMP_SANITY_CHECK 0

MEMP_SANITY_CHECK==1: run a sanity check after each memp_free() to make sure that there are no cycles in the linked lists.

#define MEMP_NUM_PBUF 64

MEMP_NUM_PBUF: the number of memp struct pbufs (used for PBUF_ROM and PBUF_REF). If the application sends a lot of data out of ROM (or other static memory), this should be set high.

#define MEMP_NUM_RAW_PCB 4

MEMP_NUM_RAW_PCB: Number of raw connection PCBs (requires the LWIP_RAW option)

#define MEMP_NUM_UDP_PCB 16

MEMP_NUM_UDP_PCB: the number of UDP protocol control blocks. One per active UDP "connection". (requires the LWIP_UDP option)

#define MEMP_NUM_TCP_PCB 16

MEMP_NUM_TCP_PCB: the number of simulatenously active TCP connections. (requires the LWIP_TCP option)

#define MEMP_NUM_TCP_PCB_LISTEN 16

#define MEMP_NUM_TCP_SEG 64

MEMP_NUM_TCP_SEG: the number of simultaneously queued TCP segments. (requires the LWIP_TCP option)

#define MEMP_NUM_REASSDATA 5

MEMP_NUM_REASSDATA: the number of simultaneously IP packets queued for reassembly (whole packets, not fragments!)

#define MEMP_NUM_ARP_QUEUE 30

MEMP_NUM_ARP_QUEUE: the number of simulateously queued outgoing packets (pbufs) that are waiting for an ARP request (to resolve their destination address) to finish. (requires the ARP_QUEUEING option)

#define MEMP_NUM_IGMP_GROUP 8

MEMP_NUM_IGMP_GROUP: The number of multicast groups whose network interfaces can be members et the same time (one per netif - allsystems group -, plus one per netif membership). (requires the LWIP_IGMP option)

#define MEMP_NUM_SYS_TIMEOUT 16

MEMP_NUM_SYS_TIMEOUT: the number of simulateously active timeouts. (requires NO_SYS==0)

#define MEMP_NUM_NETBUF 64

#define ARP_TABLE_SIZE 20

ARP_TABLE_SIZE: Number of active MAC-IP address pairs cached.

#define ARP_QUEUEING 1

ARP_QUEUEING==1: Outgoing packets are queued during hardware address resolution.

#define ETHARP_TRUST_IP_MAC 1

ETHARP_TRUST_IP_MAC==1: Incoming IP packets cause the ARP table to be updated with the source MAC and IP addresses supplied in the packet. You may want to disable this if you do not trust LAN peers to have the correct addresses, or as a limited approach to attempt to handle spoofing. If disabled, lwIP will need to make a new ARP request if the peer is not already in the ARP table, adding a little latency.

#define IP_FORWARD 0

IP_FORWARD==1: Enables the ability to forward IP packets across network interfaces. If you are going to run lwIP on a device with only one network interface, define this to 0.

#define IP_OPTIONS_ALLOWED 1

IP_OPTIONS_ALLOWED: Defines the behavior for IP options. IP_OPTIONS_ALLOWED==0: All packets with IP options are dropped. IP_OPTIONS_ALLOWED==1: IP options are allowed (but not parsed).

#define IP_REASSEMBLY 1

IP_REASSEMBLY==1: Reassemble incoming fragmented IP packets. Note that this option does not affect outgoing packet sizes, which can be controlled via IP_FRAG.

#define IP_FRAG 1

IP_FRAG==1: Fragment outgoing IP packets if their size exceeds MTU. Note that this option does not affect incoming packet sizes, which can be controlled via IP_REASSEMBLY.

#define IP_REASS_MAXAGE 3

IP_REASS_MAXAGE: Maximum time (in multiples of IP_TMR_INTERVAL - so seconds, normally) a fragmented IP packet waits for all fragments to arrive. If not all fragments arrived in this time, the whole packet is discarded.

#define IP_REASS_MAX_PBUFS 10

IP_REASS_MAX_PBUFS: Total maximum amount of pbufs waiting to be reassembled. Since the received pbufs are enqueued, be sure to configure PBUF_POOL_SIZE > IP_REASS_MAX_PBUFS so that the stack is still able to receive packets even if the maximum amount of fragments is enqueued for reassembly!

#define IP_FRAG_USES_STATIC_BUF 1

IP_FRAG_USES_STATIC_BUF==1: Use a static MTU-sized buffer for IP fragmentation. Otherwise pbufs are allocated and reference the original packet data to be fragmented.

#define IP_FRAG_MAX_MTU (1514 + MEM_ALIGNMENT)

IP_FRAG_MAX_MTU: Assumed max MTU on any interface for IP frag buffer (requires IP_FRAG_USES_STATIC_BUF==1)

#define IP_DEFAULT_TTL 255

IP_DEFAULT_TTL: Default value for Time-To-Live used by transport layers.

#define LWIP_ICMP 1

#define LWIP_SNMP 0

LWIP_SNMP==1: Turn on SNMP module. UDP must be available for SNMP transport.

#define LWIP_IGMP 1

LWIP_IGMP==1: Turn on IGMP module.

#define LWIP_DNS 1

#define DNS_MAX_SERVERS 2

The maximum number of DNS servers

#define DNS_DOES_NAME_CHECK 1

DNS_DOES_NAME_CHECK=1: DNS does name checking between the query and the response.

#define DNS_USES_STATIC_BUF 1

TCP_MAXRTX: Maximum number of retransmissions of data segments.

#define TCP_SYNMAXRTX 6

TCP_SYNMAXRTX: Maximum number of retransmissions of SYN segments.

#define TCP_QUEUE_OOSEQ 1

TCP_QUEUE_OOSEQ==1: TCP will queue segments that arrive out of order. Define to 0 if your device is low on memory.

#define TCP_MSS 1460

TCP_MSS: TCP Maximum segment size. (default is 128, a *very* conservative default.) For the receive side, this MSS is advertised to the remote side when opening a connection. For the transmit size, this MSS sets an upper limit on the MSS advertised by the remote host.

Note:: This value cannot be changed without recompilation of the MityDSP Net library!

#define TCP_CALCULATE_EFF_SEND_MSS 1

TCP_CALCULATE_EFF_SEND_MSS: The maximum size of a segment that TCP really sends, the 'effective send MSS,' MUST be the smaller of the send MSS (which reflects the available reassembly buffer size at the remote host) and the largest size permitted by the IP layer (RFC 1122) Setting this to 1 enables code that checks TCP_MSS against the MTU of the netif used for a connection and limits the MSS if it would be too big otherwise.

#define TCP_SND_BUF (16 * TCP_MSS)

TCP_SND_BUF: TCP sender buffer space (bytes).

#define TCP_SND_QUEUELEN (4 * (TCP_SND_BUF/TCP_MSS))

TCP_SND_QUEUELEN: TCP sender buffer space (pbufs). This must be at least as much as (2 * TCP_SND_BUF/TCP_MSS) for things to work.

#define TCP_SNDLOWAT (TCP_SND_BUF/2)

TCP_SNDLOWAT: TCP writable space (bytes). This must be less than or equal to TCP_SND_BUF. It is the amount of space which must be available in the TCP snd_buf for select to return writable.

#define TCP_LISTEN_BACKLOG 1

TCP_LISTEN_BACKLOG=1: Enable the backlog option for tcp listen pcb.

#define TCP_DEFAULT_LISTEN_BACKLOG 5

The maximum allowed backlog for TCP listen netconns. This backlog is used unless another is explicitly specified. 0xff is the maximum (u8_t).

#define LWIP_CALLBACK_API 1

LWIP_EVENT_API and LWIP_CALLBACK_API: Only one of these should be set to 1. LWIP_EVENT_API==1: The user defines lwip_tcp_event() to receive all events (accept, sent, etc) that happen in the system. LWIP_CALLBACK_API==1: The PCB callback function is called directly for the event.

#define PBUF_LINK_HLEN 14

PBUF_LINK_HLEN: the number of bytes that should be allocated for a link level header. The default is 14, the standard value for Ethernet.

Note:: This value cannot be changed without recompilation of the MityDSP Net library!

#define PBUF_POOL_BUFSIZE LWIP_MEM_ALIGN_SIZE(TCP_MSS+40+PBUF_LINK_HLEN+CACHE_L2_LINESIZE+VLAN_LINK_EXTEND)

PBUF_POOL_BUFSIZE: the size of each pbuf in the pbuf pool. The default is designed to accomodate single full size TCP frame in one pbuf, including TCP_MSS, IP header, and link header.

Note:: Must add an extra CACHE_L2_LINESIZE to the size to allow the packet to start one linesize into the pbuf payload. This leaves room ahead of this boundary for header padding.

#define LWIP_NETIF_HOSTNAME 0

LWIP_NETIF_HOSTNAME==1: use DHCP_OPTION_HOSTNAME with netif's hostname field.

#define LWIP_NETIF_API 1

LWIP_NETIF_API==1: Support netif api (in netifapi.c)

#define LWIP_NETIF_STATUS_CALLBACK 1

LWIP_NETIF_STATUS_CALLBACK==1: Support a callback function whenever an interface changes its up/down status (i.e., due to DHCP IP acquistion)

Note:: This value cannot be changed without recompilation of the MityDSP Net library!

#define LWIP_NETIF_LINK_CALLBACK 1

LWIP_NETIF_LINK_CALLBACK==1: Support a callback function from an interface whenever the link changes (i.e., link down)

Note:: This value cannot be changed without recompilation of the MityDSP Net library!

#define LWIP_NETIF_HWADDRHINT 0

LWIP_NETIF_HWADDRHINT==1: Cache link-layer-address hints (e.g. table indices) in struct netif. TCP and UDP can make use of this to prevent scanning the ARP table for every sent packet. While this is faster for big ARP tables or many concurrent connections, it might be counterproductive if you have a tiny ARP table or if there never are concurrent connections.

#define LWIP_HAVE_LOOPIF 1

LWIP_HAVE_LOOPIF==1: Support loop interface (127.0.0.1) and loopif.c

#define LWIP_LOOPIF_MULTITHREADING 1

LWIP_LOOPIF_MULTITHREADING: Indicates whether threading is enabled in the system, as LOOPIF must change how it behaves depending on this setting. Setting this is needed to avoid reentering non-reentrant functions like tcp_input(). LWIP_LOOPIF_MULTITHREADING==1: Indicates that the user is using a multithreaded environment like tcpip.c. In this case, netif->input() is called directly. LWIP_LOOPIF_MULTITHREADING==0: Indicates a polling (or NO_SYS) setup. The packets are put on a list and loopif_poll() must be called in the main application loop.

#define TCPIP_THREAD_NAME "tcpip_thread"

TCPIP_THREAD_NAME: The name assigned to the main tcpip thread.

#define TCPIP_THREAD_STACKSIZE 8192

TCPIP_THREAD_STACKSIZE: The stack size used by the main tcpip thread. The stack size value itself is platform-dependent, but is passed to sys_thread_new() when the thread is created.

#define TCPIP_THREAD_PRIO DSPNet_tcpip_priority

#define TCPIP_MBOX_SIZE 0

TCPIP_MBOX_SIZE: The mailbox size for the tcpip thread messages The queue size value itself is platform-dependent, but is passed to sys_mbox_new() when tcpip_init is called.

Note:: A value of zero causes sys_mbox_new() to use the default, which can be changed via DSPNetStackInit().

#define DEFAULT_THREAD_NAME "lwIP"

DEFAULT_THREAD_NAME: The name assigned to any other lwIP thread.

#define DEFAULT_THREAD_STACKSIZE 4096

DEFAULT_THREAD_STACKSIZE: The stack size used by any other lwIP thread. The stack size value itself is platform-dependent, but is passed to sys_thread_new() when the thread is created.

#define DEFAULT_THREAD_PRIO 5

#define DEFAULT_RAW_RECVMBOX_SIZE 0

DEFAULT_RAW_RECVMBOX_SIZE: The mailbox size for the incoming packets on a NETCONN_RAW. The queue size value itself is platform-dependent, but is passed to sys_mbox_new() when the recvmbox is created.

Note:: A value of zero causes sys_mbox_new() to use the default, which can be changed via DSPNetStackInit().

#define DEFAULT_UDP_RECVMBOX_SIZE 0

DEFAULT_UDP_RECVMBOX_SIZE: The mailbox size for the incoming packets on a NETCONN_UDP. The queue size value itself is platform-dependent, but is passed to sys_mbox_new() when the recvmbox is created.

Note:: A value of zero causes sys_mbox_new() to use the default, which can be changed via DSPNetStackInit().

#define DEFAULT_TCP_RECVMBOX_SIZE 0

DEFAULT_TCP_RECVMBOX_SIZE: The mailbox size for the incoming packets on a NETCONN_TCP. The queue size value itself is platform-dependent, but is passed to sys_mbox_new() when the recvmbox is created.

Note:: A value of zero causes sys_mbox_new() to use the default, which can be changed via DSPNetStackInit().

#define DEFAULT_ACCEPTMBOX_SIZE 0

DEFAULT_ACCEPTMBOX_SIZE: The mailbox size for the incoming connections. The queue size value itself is platform-dependent, but is passed to sys_mbox_new() when the acceptmbox is created.

Note:: A value of zero causes sys_mbox_new() to use the default, which can be changed via DSPNetStackInit().
