In sas2r04 spec page 103, it states the following events should use the
saturating counters
Phys shall count the following events using saturating counters and
report them in the Protocol-Specific Port
log page (see and/or the SMP REPORT PHY ERROR LOG function
a) invalid dwords received;
b) dwords received with running disparity errors;
c) loss of dword synchronization; and
d) phy reset problems.
However, on p.104, table 24, these 4-events are using counter type
"wrapping counter"
Thus, which type of counter we should use?
