menuconfig NET_LOG

	  Enable logging in various parts of the network stack.
	  Specific debugging options to other sub-menus will be unlocked
	  as well (IPv6, IPv4, ...).

	help
	  Sets log level for the network stack.
	  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
	  4 DEBUG, write SYS_LOG_DBG in addition to previous levels

	  By default, logging will apply only on enabled CONFIG_NET_DEBUG_*
	  options, on which CONFIG_SYS_LOG_NET_LEVEL would be applied.
	  However, if you want all the network stack logging enabled at once,
	  use this option. Beware logging takes a lot of ROM/RAM and kills
	  execution timing so it can affect your use case.

config NET_DEBUG_CORE
	bool "Debug core IP stack"
	help
	  Enables core network stack code part to output debug messages

config NET_DEBUG_IF
	bool "Debug network interface code"
	help
	  Enables network interface code part to output debug messages

config NET_DEBUG_TC
	bool "Debug network traffic class code"

	  Enables network traffic class code part to output debug messages

	help
	  Enables utility functions to output debug messages

	help
	  Enables printing of network context allocations and frees.

	  Enables collection of network packet and buffer allocations and frees.

	bool "Debug network packet and buffer individual allocation"
	depends on NET_DEBUG_NET_PKT
	help
	  Enables printing of network packet and buffer allocations and frees for
	  each allocation. This can produce lot of output so it is disabled by
	  default.

config NET_DEBUG_NET_PKT_EXTERNALS
	int "How many external network packet allocations"
	default 0
	depends on NET_DEBUG_NET_PKT
	help
	  How many external net_pkt objects are there in user specific pools.
	  This value is used when allocating space for tracking the
	  memory allocations.

config NET_DEBUG_CONN
	bool "Debug connection handling"
	help
	  Enables connection debug messages

config NET_DEBUG_ROUTE
	bool "Debug route management"
