Specifies the minimum time value of 'wfFddiMacTvxValue'
that shall be used by any MAC that is configured in this
path. The operational value of 'wfFddiMacTvxValue' is
managed by setting this variable. This variable has the
time value range of:
0 < wfFddiPathTvxLowerBound < wfFddiPathMaxTReq
Changes to this attribute shall either satisfy the time
value relationship:
wfFddiPathTvxLowerBound <= wfFddiMacTvxCapability
of each of the MACS currently on the path, or be
considered out of range. Time specified in nanoseconds.
The initial value of wfFddiPathTvxLowerBound shall be
2.500 msec.
