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.

For following fc_host specific attributes, vports rely on the pport. So, this patch changed way to access the data for those attributes so that they can access pport's. - get_host_speed (speed) - get_host_port_state (port_state) - get_host_port_type (port_type) - get_fc_host_stats Also, added PORT_SPEED_8GB case in the speed attribute for 8Gb HBAs.

This patch converts users of pci_enable_device_bars() to the new pci_enable_device_{io,mem} interface. The new API fits nicely, except maybe for the QLA case where a bit of code re-organization might be a good idea but I prefer sticking to the simple patch as I don't have hardware to test on. I'll also need some feedback on the cs5520 change. Signed-off-by: NBenjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by: NGreg Kroah-Hartman <gregkh@suse.de>

FCE support enables the firmware to record FC extended link services and basic link services frames which have been transmitted and received by the ISP. This allows for a limited view of the FC traffic through the ISP without using a FC analyzer. This can be useful in situations where a physical connection to the FC bus is not possible. The driver exports this information in two ways -- first, via a debugfs node exported for all supported ISPs under: <debugfs_mount_point>/qla2xxx/qla2xxx_<host_no>/fce where a read of the 'fce' file will provide a snapshot of the firmware's FCE buffer; and finally, the FCE buffer will be extracted during a firmware-dump scenario.
