2010-07-28[SCSI] ipr: fix resource type update and add sdev and shost attributesWayne Boyer
Setting the resource type in the ipr_update_res_entry function was incorrect in that the top 4 bits were masked off. The assignment has been updated to no longer mask those bits. Then, two new attributes were added to allow the user space utilities to more easily get information. The resource_type sdev attribute is set for all devices in the adapter's configuration table and indicates the type of device. The fw_type shost attribute indicates the firmware type supported by the adapter. Finally, the resource_path attribute was changed to be mode S_IRUGO.

2010-07-28[SCSI] ipr: fix transition to operational for new adaptersWayne Boyer
The method of transitioning to operational for new adapters includes using initialization stages. The current stage is indicated via a register read. The final good stage in the sequence is "operational" but does not necessarily indicate that the driver can proceed. There is another bit that gets set in the adapter->host interrupt register when the adapter has completed enough of its bringup such that it can accept commands. The driver was not checking that bit before proceeding which led to intermittent errors and adapter resets. The fix is to check the "transition to operational" bit in the interrupt register after detecting that the initialization stage is "operational" and only proceed if both are set.

2010-07-27[SCSI] bfa: vport fixesJing Huang
This patch fixes 3 bugs in vport create/delete. 1) Replace scsi_add_host() with scsi_add_host_with_dma() 2) Fix rmmod hang when there are vports configured. This is due to a race condition between the workqueue destroy in pci remove context and the vport delete works being handled. The fix is to use a counter to track the vport delete work, so that workqueue destroy will not be called until all configured vports are deleted from workqueue. 3) Fix rmmmod crash when there are PBC vport configured. PBC is not allowed to be deleted dynamically. However, if someone try to delete it, it leaves the vport is wrong state. The fix is to restore the vport back to original state when the attempt to delete pbc vport delete is failed.

2010-07-27[SCSI] bfa: fix possible IO double completionJing Huang
While processing the ioim in callback functions, the ioim is still in io_q. During this time, if the itnim goes offline, the ioim is requeued from itnim->io_q into itnim->delay_comp_q although the request is already completed. This results in requeing the ioim into the callback queue if the ioim is not freed by the time the ioim is requeued. This results in double completion of the ioim. To fix this, whenever a response is received from firmware for an ioim, deque it from io_q and enque to fcpim->comp_q. This will eliminate any possibility of itnim picking any ioim for which the response is already received.

2010-07-27[SCSI] bfa: fix link state structureJing Huang

But the size of this structure(164 bytes) is larger than the reserved RME buffer size(128 byes). The following changes reduce the size of the structure to be less than RME buffer size(128 bytes): - Remove the trunk and loop info from link_state structure, because both trunk and loop are not supported. - Combine qos_vc_attr and fcf into an union.
