Controls the interpretation of the MTU field in the
database description packet header. Per RFC 2178 the
MTU indicates the largest size IP packet that an OSPF
interface can receive. If the MTU is greater than that
which the interface can receive the packet is ignored
and thus, an adjacency is not formed. In RFC 1583 this
field does not exist. The value 'enabled' denotes RFC
2178 processing of the MTU field. The value 'disabled'
denotes RFC 1583 processing.
