[802.3_ISAAC] Section related to 1 second time to enter LPI mode for EEE

All,

Following are the sections that prevent PHYs supporting EEE from entering low power mode (in either direction) for 1 second in the beginning.


78.1.2.1.2 Semantics of the service primitive



The semantics of the service primitive are as follows:

LP_IDLE.request (LPI_REQUEST)

The LPI_REQUEST parameter can take one of two values: ASSERT or DEASSERT. ASSERT initiates the

signaling of LPI to the link partner. DEASSERT stops the signaling of LPI to the link partner. The effect of

receipt of this primitive is undefined in any of the following cases:

a) link_status is not OK (see 28.2.6.1.1)

b) LPI_REQUEST=ASSERT within 1 s of the change of link_status to OK

c) The PHY is indicating LOCAL FAULT

d) The PHY is indicating REMOTE FAULT


46.4.1 LPI messages

LP_IDLE.indication(LPI_INDICATION)
A primitive that indicates to the LPI client that the PHY has detected the assertion or de-assertion
of LPI from the link partner.
Values: DEASSERT: The link partner is operating with normal interframe behavior (default).
ASSERT: The link partner has asserted LPI.

LP_IDLE.request(LPI_REQUEST)
The LPI_REQUEST parameter can take one of two values: ASSERT or DE-ASSERT. ASSERT
initiates the signaling of LPI to the link partner. DE-ASSERT stops the signaling of LPI to the link
partner. The effect of receipt of this primitive is undefined if link_status is not OK (see 28.2.6.1.1)
or within 1 s of the change of link_status to OK.


Thanks
