The Resource_Allocation_Timeout Value used for FxPorts
as the timeout value for determining when to reuse an
NxPort resource such as a Recovery_Qualifier. It
represents E_D_TOV (fcTimerEdtov) plus twice the
maximum time that a frame may be delayed within the
Fabric and still be delivered.
Note that all switches in a fabric should be configured
with the same value of this timeout.
