>From clause 4.2.8 of SAS2r14 there is only one PHY IDENTIFIER per
physical phy and the logical phys are associated with the same PHY
Identifier.  This means that phy events cannot be counted on individual
logical phys.  Is it the intent that all counts be an aggregation of the
counts for the logical phys within a phy?  Based on the responses to
this, I will generate clarifying letter ballot comments.
Thanks for any input,
