# # For a description of the syntax of this configuration file, # see misc/tools/kconfig-language.txt. # config NET bool "Networking support" default n ---help--- Enable or disable all network features config ARCH_HAS_PHY bool if NET choice prompt "Board PHY Selection" depends on ARCH_HAS_PHY default PHY_KS8721 config PHY_KS8721 bool "Micrel KS8721 PHY" config PHY_DP83848C bool "National Semiconduction DP83848C PHY" config PHY_LAN8720 bool "SMSC LAN8720 PHY" endchoice config NET_NOINTS bool "Not interrupt driven" default n ---help--- NET_NOINT indicates that uIP not called from the interrupt level. If NET_NOINTS is defined, critical sections will be managed with semaphores; Otherwise, it assumed that uIP will be called from interrupt level handling and critical sections will be managed by enabling and disabling interrupts. config NET_MULTIBUFFER bool "Use multiple device-side I/O buffers" default n ---help--- Traditionally, uIP has used a single buffer for all incoming and outgoing traffic. If this configuration is selected, then the driver can manage multiple I/O buffers and can, for example, be filling one input buffer while sending another output buffer. Or, as another example, the driver may support queuing of concurrent input/ouput and output transfers for better performance. config NET_IPv6 bool "IPv6" default n ---help--- Build in support for IPv6. Not fully implemented. config NSOCKET_DESCRIPTORS int "Number of socket descriptor" default 8 ---help--- Maximum number of socket descriptors per task/thread. config NET_NACTIVESOCKETS int "Max socket operations" ---help--- Maximum number of concurrent socket operations (recv, send, etc.). Default: NET_TCP_CONNS+NET_UCP_CONNS config NET_SOCKOPTS bool "Socket options" default n ---help--- Enable or disable support for socket options config NET_BUFSIZE int "Network packet size" default 562 if !NET_TCP && NET_UDP && !NET_SLIP default 420 if NET_TCP && !NET_UDP && !NET_SLIP default 296 if NET_SLIP ---help--- uIP buffer size. Default: 562 config NET_TCPURGDATA bool "Urgent data" default n ---help--- Determines if support for TCP urgent data notification should be compiled in. Urgent data (out-of-band data) is a rarely used TCP feature that is very seldom would be required. config NET_TCP bool "TCP/IP Networking" default n ---help--- TCP support on or off endif if NET_TCP config NET_TCP_CONNS int "Number of TCP/IP connections" default 8 ---help--- Maximum number of TCP/IP connections (all tasks) config NET_MAX_LISTENPORTS int "Number of listening ports" default 20 ---help--- Maximum number of listening TCP/IP ports (all tasks). Default: 20 config NET_TCP_READAHEAD_BUFSIZE bool "TCP/IP read-ahead buffer size" default 562 ---help--- Size of TCP/IP read-ahead buffers config NET_NTCP_READAHEAD_BUFFERS int "Number of TCP/IP read-ahead buffers" default 8 ---help--- Number of TCP/IP read-ahead buffers (may be zero) config NET_TCPBACKLOG bool "TCP/IP backlog support" default n ---help--- Incoming connections pend in a backlog until accept() is called. The size of the backlog is selected when listen() is called. endif config NET_UDP bool "UDP Networking" default n depends on NET ---help--- Enable or disable UDP networking support. if NET_UDP config NET_UDP_CHECKSUMS bool "UDP checksums" default n ---help--- Enable/disable UDP checksum support config NET_UDP_CONNS int "Number of UDP sockets" default 8 ---help--- The maximum amount of open concurrent UDP sockets config NET_BROADCAST bool "UDP broadcast Rx support" default n ---help--- Incoming UDP broadcast support endif config NET_ICMP bool "ICMP networking support" default n depends on NET ---help--- Enable minimal ICMP support. Includes built-in support for sending replies to received ECHO (ping) requests. if NET_ICMP config NET_ICMP_PING bool "ICMP ping interfaces" default n ---help--- Provide interfaces to support application level support for for sending ECHO (ping) requests and associating ECHO replies. config NET_PINGADDRCONF bool "Ping address configuration" default n ---help--- Use "ping" packet for setting IP address endif config NET_IGMP bool "IGMPv2 clientsupport" default n depends on NET ---help--- Enable IGMPv2 client support. if NET_IGMP config PREALLOC_IGMPGROUPS int "Number of pre-allocated IGMP groups" default 4 ---help--- Pre-allocated IGMP groups are used only if needed from interrupt level group created (by the IGMP server). Default: 4. endif if NET config NET_STATISTICS bool "Collect network statistics" default n ---help--- uIP statistics on or off config NET_RECEIVE_WINDOW int "Receive window size" ---help--- The size of the advertised receiver's window config NET_ARPTAB_SIZE int "ARP table size" default 16 ---help--- The size of the ARP table config NET_ARP_IPIN bool "ARP address harvesting" default n ---help--- Harvest IP/MAC address mappings from the ARP table from incoming IP packets. config NET_MULTICAST bool "Multi-cast Tx support" default n ---help--- Outgoing multi-cast address support config NET_FWCACHE_SIZE int "FW cache size" ---help--- Number of packets to remember when looking for duplicates config NET_SLIP bool "SLIP support" default n ---help--- Enables building of the SLIP driver. SLIP requires at least one IP protocol selected and the following additional network settings: NET_NOINTS and NET_MULTIBUFFER. NET_BUFSIZE *must* be set to 296. Other optional configuration settings that affect the SLIP driver: NET_STATISTICS. Default: Ethernet SLIP supports point-to-point IP communications over a serial port. The default data link layer for uIP is Ethernet. If NET_SLIP is defined in the NuttX configuration file, then SLIP will be supported. The basic differences between the SLIP and Ethernet configurations is that when SLIP is selected: * The link level header (that comes before the IP header) is omitted. * All MAC address processing is suppressed. * ARP is disabled. If NET_SLIP is not selected, then Ethernet will be used (there is no need to define anything special in the configuration file to use Ethernet -- it is the default). endif if NET_SLIP config SLIP_NINTERFACES int "Number of SLIP interfaces" default 1 ---help--- Selects the number of physical SLIP interfaces to support. Default: 1 config SLIP_STACKSIZE int "SLIP stack size" default 2048 ---help--- Select the stack size of the SLIP RX and TX tasks. Default: 2048 config SLIP_DEFPRIO int "SLIP priority" default 128 ---help--- The priority of the SLIP RX and TX tasks. Default: 128 endif
