[SCSI] lpfc: bug fixes
Following the NPIV support, the following changes have been accumulated in the testing and qualification of the driver: - Fix affinity of ELS ring to slow/deferred event processing - Fix Ring attention masks - Defer dev_loss_tmo timeout handling to worker thread - Consolidate link down error classification for better error checking - Remove unused/deprecated nlp_initiator_tmr timer - Fix for async scan - move adapter init code back into pci_probe_one context. Fix async scan interfaces. - Expand validation of ability to create vports - Extract VPI resource cnt from firmware - Tuning of Login/Reject policies to better deal with overwhelmned targets - Misc ELS and discovery fixes - Export the npiv_enable attribute to sysfs - Mailbox handling fix - Add debugfs support - A few other small misc fixes: - wrong return values, double-frees, bad locking - Added adapter failure heartbeat Signed-off-by: James Smart <James.Smart@emulex.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>

52 * To access this interface the user should:
53 * # mkdir /debug
54 * # mount -t debugfs none /debug
55 *
56 * The lpfc debugfs directory hierachy is:
57 * lpfc/lpfcX/vportY

59 * where Y is the vport VPI on that hba

62 * discovery_trace
63 * This is an ACSII readable file that contains a trace of the last
64 * lpfc_debugfs_max_disc_trc events that happened on a specific vport.
65 * See lpfc_debugfs.h for different categories of
66 * discovery events. To enable the discovery trace, the following
67 * module parameters must be set:
68 * lpfc_debugfs_enable=1 Turns on lpfc debugfs filesystem support
69 * lpfc_debugfs_max_disc_trc=X Where X is the event trace depth for
70 * EACH vport. X MUST also be a power of 2.
71 * lpfc_debugfs_mask_disc_trc=Y Where Y is an event mask as defined in
72 * lpfc_debugfs.h .
