A hardware problem on a FICON link is reported by the Channel Subsystem to the operating system via a Link Incident Record (LIR). In response, the operating system should issue a message that enables hardware service personnel to identify and repair the failing component. Current Linux LIR handling is broken because LIR data is incorrectly interpreted and no log message is generated. This patch fixes Linux LIR handling by implementing a new log message for LIRs indicating a degraded or non-operational link. Also LIRs are no longer used to deactivate channel paths because the available data does not reliably allow to determine the affected channel path.
