[802.3AZ] 802.3az Draft 2.0 comments 466 and 130 question

Two comments are requesting consolidation of the control code value for
/LI/ in clauses 49 and 55. Clause 49 specifies 10GBASE-R /LI/ control
code is 0x07 and Clause 55 specifies 0x06. Comment 130 suggests changing
the 10GBASE-R /LI/ control code to 0x06, while comment 466 suggests
changing the 10GBASE-T /LI/ control code to 0x07.

For reference, the XGMII /LI/ control code is 0x06, the XGMII /I/
control code is 0x07, and the 10GBASE-R and 10GBASE-T control code for
/I/ is 0x00.

Based on the above information, the logical choice would be to use 0x06
for /LI/ for both 10GBASE-T and 10GBASE-R. This way the 10GBASE-T/R /LI/
control code value matches the XGMII /LI/ control code value. Also,
choosing 0x06 avoids confusing of the PCS /LI/ control code with the
XGMII /I/ control code.

To help understand the implications of either choice, I would like to
know what the rationale was for picking the control codes that are in
the current draft.

Subject: [802.3AZ] Draft 2.0 ballot result

Dear colleagues,

The result for initial Working Group Ballot on Draft 2.0 of IEEE
P802.3az is as follows:

Voters                        208
Approve                       94
Disapprove with comment       21
Disapprove without comment    0
Abstain                       25
Returns                       140

Response Rate     67.31%
Approval Rate     81.74%
Abstain Rate      17.86%

Since the Response Rate exceeded 50% by the closing date, the ballot
closed on time and since the Abstain Rate was < 30% the ballot is valid.
Since the Approval Rate exceeded 75%,  the draft stands approved.  I
would like to thank the voters for taking the time to review the draft.
This is a significant step in advancing the standard towards completion.

There were 483 comments submitted, 197 E/ERs and 286 T/TRs  Depending on
how things go, we may have to extend the meeting time into the evening
in order to process the comments, although I hope that isn't necessary. 
  I look forward to a productive meeting in Chicago.

Best regards,


Michael J. Bennett
