If network based syslog backend is enabled in Kconfig file, then syslog messages are sent to external system using UDP. See RFC 5424 and RFC 5426 for details about the syslog protocol. Signed-off-by: Jukka Rissanen <jukka.rissanen@linux.intel.com>

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
