Hi Randy,

Sorry for the delay.

Either one way or the other.  "negotiation of the PHY", "supported/
advertised (link modes) of the PHY".  Both are posessive, so the first
is a mistake but I don't agree with removing the posessive apostrophy
in the second case.

Software engineers endlessly like to create TLAs, so it could mean
both, but in this case it's the official definition from the SFF/
SNIA documents, e.g.:

                          INF-8074i Specification for

                 SFP (Small Formfactor Pluggable) Transceiver

note, no hyphen!
