The administrative module status of LLDP module.
This enables or disables LLDP in the system. A value of
'enabled' (1) indicates that LLDP is enabled in the device
and can be enabled port-wise. A value of 'disabled' (2)
indicates that LLDP is disabled in the device and also
disabled on all ports.
When LLLDP module status is changed from enabled to disabled,
a global timer (instead of port specific timers) is started
to ensure the successful transmission of shutdown frame on
all ports. Module status change from disabled to enabled is
not allowed when the global timer is running (i.e., when disable
is in progress).
