Count of soft errors; these are errors
which have been recovered. This includes
CRC errors received, frames which were
retransmitted for any reason (NAK received
or the wrong ACK received), etc. This count
is a measure of the quality of the port/line,
but should be considered in relation to the
amount of traffic on the port (frames
or bytes sent and received).
This count includes all control unit soft
errors on this port, plus errors which were
not for a specific control unit.
