Serial PMA/PMD delay limits
Serial PMD-ers,
You may not have noticed a criterion for the PMA or PMD hiding in clause 44,
which isn't helpful!
We need to air this (delay maximum) in the PMD tracks and add
cross-references in clauses 51, 52 and 54.
As to table 44-2, saying that "Serial PMD ... Includes serial PMA and PMD,
..." is wrong, surely? Should that read "Serial PHY ... Includes serial PMA
and PMD, ..." ?
