The original code to 'resize request-queues' based on iocb-counts and employed during early ISP23xx testing was too overly-pessimistic with regards to latencies in the firmware pulling requests. Recent ISPs can easily keep up processing a stream of commands from an abbreviated (effectively, half the original size) queue.

Ensure that an ISP-abort has completed before performing any update. After the update do not wait for an ISP-abort completion, instead just wait until the ISP is reset.

Given the low-level interface varies from one flash-part manufacturer to the next, the Flash-Access-Control (FAC) mailbox command makes the specific flash type transparent to the driver by encapsulating a basic set of accessor and update routines. Use these new routines where applicable by querying FAC opcode get-sector-size at init-time.

To ensure smooth operations amongst the FCoE and NIC side components of the ISP81xx chip, the FCoE driver (qla2xxx) must ensure the 10gb NIC driver (qlge) does not timeout waiting for IDC (Inter-Driver Communication) acknowledgments. The acknowledgment requirements are trivial -- a simple mirroring of incoming mailbox registers during the AEN to a process-context capable mailbox command.

Following changes have been made. 1. qla_hw_data structure holds an array for request queue pointers, and an array for response queue pointers. 2. The base request and response queues are created by default. 3. Additional request and response queues are created at the time of vport creation. If queue resources are exhausted during vport creation, newly created vports use the default queue. 4. Requests are sent to the request queue that the vport was assigned in the beginning. 5. Responses are completed on the response queue with which the request queue is associated with.

Following changes have been made to the qla2xxx FC driver in preparation for the multi- queue and future SR IOV hardware. 1. scsi_qla_host structure has been changed to contain scsi host specific data only. 2. A new structure, qla_hw_data is created to contain HBA specific hardware data. 3. Request and response IO specific data strucures are created. 4. The global list of fcports for the hba is not maintained anymore, instead a fcport list is construted on per scsi_qla_host.

During internal testing, we've seen issues (hangs) with the 'deferred' vport tear-down-processing typically accompanied with the fc_remove_host() call. This is due to the current implementation's back-end vport handling being performed by the physical-HA's DPC thread where premature shutdown could lead to latent vport requests without a processor. This should also address a problem reported by Gal Rosen (http://marc.info/?l=linux-scsi&m=121731664417358&w=2) where the driver would attempt to awaken a previously torn-down DPC thread from interrupt context by implicitly calling wake_up_process() rather than the driver's qla2xxx_wake_dpc() helper. Rather, than reshuffle the remove_one() device-removal code, during unload, depend on the driver's timer to wake-up the DPC process, by limiting wake-ups based on an 'unloading' flag.

Now that infrastructure is present within the midlayer and there is a clear distinction between what is expected from a device and target reset, convert the current device-reset codes to a target-reset, and add codes to perform a proper device-reset (LUN reset). In the process of adding reset support, collapse and consolidate large sections of mailbox-command (TMF issuance) codes, generalize the two 'wait-for-commands-to-complete' functions, and add a generic-reset routine for use by midlayer reset functions.
