The value of the object tmnxLocUsrDbDhcpUseClientPool specifies
if the IP address pool used to search for an IP address for this
host is to be indicated by the vendor-specific sub-option 13
of the DHCP option 82.
If the value of this object is set to 'true (1)', the IP address pool
indicated by the sub-option 13 is used.
This object can only be set to 'true (1)' when the value of
tmnxLocUsrDbDhcpAddrType is 'unknown (0)' and tmnxLocUsrDbDhcpPool
contains the empty string.
