config NET
bool "Networking support"
default n
---help---
Enable or disable all network features
if NET
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
