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 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_RXAVAIL
	bool "Driver-based UDP backlog"
	default n
	---help---
		One problem with UDP communications is that, unlike TCP/IP, there is
		no backlog of UDP packets.  So if you are listening at the precise
		moment that the UDP packet is sent, it will not be received.  This
		is not incompatible with the properties of UDP, but can result in
		bad performance if packets are missed, time out, and are resent.

		Some Ethernet controllers have built-in RAM and the drivers can
		support retention of UDP packets in that RAM.  If the drivers
		supports such a capability, this option may be enabled to use it.
		NOTE:  If this option is enabled, the driver must support the
		rxavail() method in the net_driver_s structure.

config NET_UDP_READAHEAD
	bool "Enable UDP/IP read-ahead buffering"
	default y
