2011-12-12[SCSI] qla2xxx: Remove qla2x00_wait_for_loop_ready function.Saurav Kashyap
This function can wait for 5min under certain scenarios. One of them is when the port is down from switch and bus reset is issued. The bus reset used to wait for 5 minutes for the loop and upper layer callers used to hang and give stack trace because of getting stuck for 120 sec. It is legacy code that was used when the driver used to do queuing of the commands.

2011-10-30[SCSI] qla2xxx: Correct inadvertent clearing of RISC_INTR status.Andrew Vasquez
During heavy I/O (CPU-affinity mode enabled) and CLI/Agent interactions, the driver would report periodic mailbox command timeout statuses. Within the CPU-affinity ISR handler, the driver should check the 'disable-msix-handshake' flag in deciding whether or not to clear HCCRX_CLR_RISC_INT. The mode is not specific to a dedicated queue, instead, applies to the current 'ha' context.

2011-10-02[SCSI] qla2xxx: Fix crash in qla2x00_abort_all_cmds() on unloadRoland Dreier
I hit a crash in qla2x00_abort_all_cmds() if the qla2xxx module is unloaded right after it is loaded. I debugged this down to the abort handling improperly treating a command of type SRB_ADISC_CMD as if it had a bsg_job to complete when that command actually uses the iocb_cmd part of the union. (I guess to hit this one has to unload the module while the async FC initialization is still in progress) It seems we should only look for a bsg_job if type is SRB_ELS_CMD_RPT, SRB_ELS_CMD_HST or SRB_CT_CMD, so switch the test to make that explicit.

2011-08-27[SCSI] qla2xxx: T10 DIF - Fix incorrect error reporting.Arun Easi
This fix: - Disables app tag peeking; correct tag check will be added when the SCSI API is available. - Always derive ref_tag from scsi_get_lba() - Removes incorrect swap of FCP_LUN in FCP_CMND - Moves app-tag error check before ref-tag check. The reason being, currently there is no interface in SCSI to retrieve the app-tag for protection I/Os, so driver puts zero for app-tag in the firmware interface, but requests not to validate it, but when a ref-tag error is detected by firmware, it would put expected/actual tags for all the protection tags (guard/app/ref). As driver checks for app tag error first, a ref-tag error is incorrectly flagged as app-tag error. - Convert HBA specific checks to capability based.
