- menu "UDP Networking"
- config NET_UDP
- bool "UDP Networking"
- default n
- depends on NET
- ---help---
- Enable or disable UDP networking support.
- config NET_UDP_NO_STACK
- bool "Disable UDP/IP Stack"
- default n
- select NET_UDP
- ---help---
- Build without UDP/IP stack even if UDP networking support enabled.
- if NET_UDP && !NET_UDP_NO_STACK
- config NET_UDP_BINDTODEVICE
- bool "UDP Bind-to-device support"
- default n
- select NET_UDPPROTO_OPTIONS
- select NETDEV_IFINDEX
- ---help---
- Enable support for the UDP_BINDTODEVICE socket option.
- Linux has SO_BINDTODEVICE but in NuttX this option is instead
- specific to the UDP protocol.
- config NET_UDP_CHECKSUMS
- bool "UDP checksums"
- default y if NET_IPv6
- default n if !NET_IPv6
- ---help---
- Enable/disable UDP checksum support. UDP checksum support is
- REQUIRED for IPv6.
- 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
- config NET_UDP_READAHEAD
- bool "Enable UDP/IP read-ahead buffering"
- default y
- select NET_READAHEAD
- select MM_IOB
- config UDP_READAHEAD_NOTIFIER
- bool "Support UDP read-ahead notifications"
- default n
- depends on NET_UDP_READAHEAD && SCHED_WORKQUEUE
- select WQUEUE_NOTIFIER
- ---help---
- Enable building of UDP read-ahead notifier logic that will execute a
- worker function on the high priority work queue when read-ahead data
- is available. This is is a general purpose notifier, but was
- developed specifically to support poll() logic where the poll must
- wait for read-ahead data to become available.
- config NET_UDP_WRITE_BUFFERS
- bool "Enable UDP/IP write buffering"
- default n
- select NET_WRITE_BUFFERS
- select MM_IOB
- ---help---
- Write buffers allows buffering of ongoing UDP/IP packets, providing
- for higher performance, streamed output.
- You might want to disable UDP/IP write buffering on a highly memory
- memory constrained system where there are no performance issues.
- if NET_UDP_WRITE_BUFFERS
- config NET_UDP_NWRBCHAINS
- int "Number of pre-allocated I/O buffer chain heads"
- default 8
- ---help---
- These tiny nodes are used as "containers" to support queuing of
- UDP write buffers. This setting will limit the number of UDP write
- operations that can be "in-flight" at any give time. So a good
- choice for this value would be the same as the maximum number of
- UDP connections.
- config NET_UDP_WRBUFFER_DEBUG
- bool "Force write buffer debug"
- default n
- depends on DEBUG_FEATURES
- select IOB_DEBUG
- ---help---
- This option will force debug output from UDP write buffer logic,
- even without network debug output. This is not normally something
- that would want to do but is convenient if you are debugging the
- write buffer logic and do not want to get overloaded with other
- network-related debug output.
- config NET_UDP_WRBUFFER_DUMP
- bool "Force write buffer dump"
- default n
- depends on DEBUG_NET || NET_UDP_WRBUFFER_DEBUG
- select IOB_DEBUG
- ---help---
- Dump the contents of the write buffers. You do not want to do this
- unless you really want to analyze the write buffer transfers in
- detail.
