DHCP: include Subnet Mask option parameter in DHCPREQUEST

Browse Source 
DHCP REQUEST from DHCP plugin does not include Subnet Mask option parameter (1). Some DHCP servers need that option to be explicit in order to return it in a DHCPACK message.
If not, DHCP plugin returns "DHCP option Subnet Mask not found in DHCPACK" error msg in this type of scenario.
