	  This option enables support for generic network protocol
	  buffers.

config NET_BUF_USER_DATA_SIZE
	int "Size of user_data available in every network buffer"
	default 4
	range 0 65535
	help
	  Amount of memory reserved in each network buffer for user data. In
	  most cases this can be left as the default value.

config NET_BUF_LOG
	bool "Network buffer logging"
	select SYS_LOG
	default n
	help
	  Enable logs and checks for the generic network buffers.

	int
	prompt "Network buffer Logging level"
	depends on SYS_LOG
	default 1
	range 0 4
	help
	  Sets log level for network buffers.
	  Levels are:
	  0 OFF, do not write
	  1 ERROR, only write SYS_LOG_ERR
	  2 WARNING, write SYS_LOG_WRN in addition to previous level
	  3 INFO, write SYS_LOG_INF in addition to previous levels

	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.

	select SYS_LOG
	default n
	help
	  Enable extra debug logs and checks for the generic network buffers.

	  * 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
