Used to configure the minimum packet length that the PFP is expected to receive. If
the packet length is less than LEN_MIN, then the event is detected by the PFP and
forwarded to PMON. The value in LEN_MIN does not affect the behavior of the data
path and is only intended for diagnostics purposes.
Used to configure the maximum packet length that the PFP is expected to receive. If
the packet length is greater than LEN_MAX, then the event is detected by PFP and
forwarded to PMON. The value in LEN_MAX does not affect the behavior of the
data path and is only intended for diagnostics purposes.
