By using EEE power savings can be achieved at the expense of traffic latency. This latency
occurs due to that the circuits EEE turn off to save power, need time to boot up before
sending traffic over the link. This time is called "wakeup time". To achieve minimal
latency, devices can use LLDP to exchange information about their respective tx and rx
"wakeup time ", as a way to agree upon the minimum wakeup time they need.
Function name:

The port on which LLDP frames are received or
transmitted.
The link partner's maximum time that transmit path can
hold-off sending data after deassertion of LPI.
The link partner's time that receiver would like the
transmitter to hold-off to allow time for the receiver to wake
from sleep.
The link partner's fallback receive Tw.
A receiving link partner may inform the transmitter of an
alternate desired Tw_sys_tx. Since a receiving link partner
is likely to have discrete levels for savings, this provides the
transmitter with additional information that it may use for a
more efficient allocation. Systems that do not implement
this option default the value to be the same as that of the
Receive Tw_sys_tx.
The link partner's Echo Tx Tw value.
The respective echo values shall be defined as the local link
partner reflection (echo) of the remote link partners
respective values. When a local link partner receives its
