2023-09-05scsi: qla2xxx: Fix NULL vs IS_ERR() bug for debugfs_create_dir()Jinjie Ruan1-3/+3
Since both debugfs_create_dir() and debugfs_create_file() return ERR_PTR and never NULL, use IS_ERR() instead of checking for NULL.

2023-07-23scsi: qla2xxx: Fix erroneous link up failureQuinn Tran2-2/+7
Link up failure occurred where driver failed to see certain events from FW indicating link up (AEN 8011) and fabric login completion (AEN 8014). Without these 2 events, driver would not proceed forward to scan the fabric. The cause of this is due to delay in the receive of interrupt for Mailbox 60 that causes qla to set the fw_started flag late. The late setting of this flag causes other interrupts to be dropped. These dropped interrupts happen to be the link up (AEN 8011) and fabric login completion (AEN 8014). Set fw_started flag early to prevent interrupts being dropped.

2023-07-23scsi: qla2xxx: Fix command flush during TMFQuinn Tran3-39/+45
For each TMF request, driver iterates through each qpair and flushes commands associated to the TMF. At the end of the qpair flush, a Marker is used to complete the flush transaction. This process was repeated for each qpair. The multiple flush and marker for this TMF request seems to cause confusion for FW. Instead, 1 flush is sent to FW. Driver would wait for FW to go through all the I/Os on each qpair to be read then return. Driver then closes out the transaction with a Marker.
