	bool "Network buffer support"
	help
	  This option enables support for generic network protocol
	  buffers.

	bool "Network buffer logging"
	select LOG
	help
	  Enable logs and checks for the generic network buffers.

config NET_BUF_WARN_ALLOC_INTERVAL
	int "Interval of Network buffer allocation warnings"
	default 1
	range 0 60
	help
	  Interval in seconds of Network buffer allocation warnings which are
	  generated when a buffer cannot immediately be allocated with K_FOREVER
	  which may lead to deadlocks. Setting it to 0 makes warnings to be
	  printed only once per allocation.

config NET_BUF_SIMPLE_LOG
	bool "Network buffer memory debugging"
	select LOG
	help
	  Enable extra debug logs and checks for the generic network buffers.

endif # NET_BUF_LOG

config NET_BUF_POOL_USAGE
	bool "Network buffer pool usage tracking"
	help
	  Enable network buffer pool tracking. This means that:
	  * amount of free buffers in the pool is remembered
	  * total size of the pool is calculated
	  * pool name is stored and can be shown in debugging prints

config NET_BUF_ALIGNMENT
	int "Network buffer alignment restriction"
	default 0
	help
	  Alignment restriction for network buffers. This is useful for
	  some hardware IP with DMA that requires the buffers to be aligned
	  to a certain byte boundary, or dealing with cache line restrictions.
	  Default value of 0 means the alignment will be the size of a void pointer,
	  any other value will force the alignment of a net buffer in bytes.

config NETWORKING
	bool "Link layer and networking (including IP)"
	select NET_BUF
	select POLL
	select ENTROPY_GENERATOR
	help
	  This option enables generic link layer and networking support
	  and is the basis for higher level protocols (e.g. IP protocols).
