Set the number of request queues to the module paramater
ql2xmaxqueues. Each vport gets a request queue. The QoS value
set to the request queues determines priority control for queued
IOs. If QoS value is not specified, the vports use the default
queue 0.

Original code would not read request/response queue pointers.
Also, collapse code into a helper qla25xx_copy_mq() function in
preparation for newer ISP parts.

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.

Use the more efficient read-DMA'ble-buffer mailbox commands
rather than reading a single word/dword at a time. We also
remove a bulk of the duplicate mailbox command-handling codes in
favor of more generic read-memory() routines (qla2xxx_dump_ram()
and qla24xx_dump_ram()).

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.

A driver must wait 100us before attempting an MMIO operation
to the RISC after a soft-reset has been initiated. A
similar delay was needed with earlier ISPs.
Note: a PCI config-space read is used to flush the MMIO
write to the ISP, since the ISP's state machines are unable
to respond to any MMIO read during the reset process.

scsi_cmnd->serial_number_at_timeout doesn't serve any purpose
anymore. All serial_number == serial_number_at_timeout tests
are always true in abort callbacks. Kill the field. Also, as
->pid always equals ->serial_number and ->serial_number
doesn't have any special meaning anymore, update comments
above ->serial_number accordingly. Once we remove all uses of
this field from all lldd's, this field should go.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
