The code is changed to support the new dynamic logging infrastructure. Following are the levels added. Default is 0 - no logging. 0x40000000 - Module Init & Probe. 0x20000000 - Mailbox Cmnds. 0x10000000 - Device Discovery. 0x08000000 - IO tracing. 0x04000000 - DPC Thread. 0x02000000 - Async events. 0x01000000 - Timer routines. 0x00800000 - User space. 0x00400000 - Task Management. 0x00200000 - AER/EEH. 0x00100000 - Multi Q. 0x00080000 - P3P Specific. 0x00040000 - Virtual Port. 0x00020000 - Buffer Dump. 0x00010000 - Misc. 0x7fffffff - For enabling all logs, can be too many logs. Setting ql2xextended_error_logging module parameter to any of the above value, will enable the debug for that particular level. Do LOGICAL OR of the value to enable more than one level.
