read link status (RLS) error counts

Link errors that have been detected in the traffic flow between components on a Fibre Channel loop. The detected errors are represented as a count (32-bit field) of error occurrences that have accumulated over time. The detected errors also help to provide a coarse measure of the integrity of the components and devices on the loop.Error count types include link failure (LF), loss of synchronization (LOS), loss of signal (LOSG), primitive sequence protocol (PSP), and invalid cyclic redundancy check (ICRC).
