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

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

Enables network interface code part to output debug messages

Enables utility functions to output debug messages

help
Enables printing of network context allocations and frees.

help
Enables collection of network packet and buffer allocations and frees.
config NET_DEBUG_NET_PKT_ALL

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.

How many external net_pkt objects are there in user specific pools.
This value is used when allocating space for tracking the
memory allocations.

help
Enables connection debug messages
config NET_DEBUG_ROUTE

Enables routing engine debug messages
