	help
	  Sets log level for modules which don't specify it explicitly. When
	  set to 0 it means log wont be activated for those modules.
	  Levels are:

	  Forces a minimum log level for all modules. Modules use their
	  specified level if it is greater than this option, otherwise they use
	  the level specified by this option instead of their default or
	  whatever was manually set.
	  Levels are:
	  0 OFF, do not override
	  1 ERROR, override to write SYS_LOG_ERR
	  2 WARNING, override to write SYS_LOG_WRN in addition to previous level

	  This can be either IPv4 or IPv6 address.
	  Server listen UDP port number can be configured here too.
	  Following syntax is supported:
	  192.0.2.1:514
	  192.0.2.42

config SYS_LOG_BACKEND_NET_MAX_BUF_SIZE
	int "Max syslog message size"
	range 64 1180
	default 256
	help
	  As each syslog message needs to fit to UDP packet, set this value
	  so that messages are not truncated.
	  The RFC 5426 recommends that for IPv4 the size is 480 octets and for
	  IPv6 the size is 1180 octets. As each buffer will use RAM, the value
	  should be selected so that typical messages will fit the buffer.
	  The total allocated memory will be
	  SYS_LOG_BACKEND_NET_MAX_BUF * SYS_LOG_BACKEND_NET_MAX_BUF_SIZE
