This attribute indicates the total number of BIP-8 Errors, framing
pattern octet errors, and path overhead identification errors detected
in received PLCP frames.
Counting of PLCP CV is inhibited for second intervals where PLCP
Severely Errored Framing Seconds (SEFS) or PLCP Unavailable
Seconds (UAS) are counted.
This attribute is a non-negative integer which monotonically
increases until it reaches a maximum value, at which point it wraps
around and starts increasing again from zero.
