Add definitions for Siklu EtherHaul ( https://www.siklu.com/ )
includes/definitions/os.inc.php :

//Siklu EH

$os = "sikluos";

$config['os'][$os]['text']                  = "Siklu EtherHaul";

$config['os'][$os]['sysObjectID'][]         = ".1.3.6.1.4.1.31926";

$config['os'][$os]['type']                  = "wireless";

Planning to add version polling, temperature, voltage later.

P.S. Don't totally understand what is for type "wireless" and what is for type "radio"?
