00a537b820 [SCSI] qla2xxx: Correct usage of inconsistent timeout values while issuing ELS commands.
The original code would incorrectly hardcode ELS timeout values
rather than using the traditional '2 * r_a_tov' value.  In some
cases, the hardcoded values would be larger than the
mailbox-command-timeout and result in a needless BIG_HAMMER (ISP
reset), the typical recovery mechanism employed in such cases.

The second defect in the original code was in the assignment of
the default 'ha->r_a_tov' to twice the traditional value.
Correct this by setting the value to 10 seconds.

3e8ce320cf [SCSI] qla2xxx: Correct discrepancies during OVERRUN handling on FWI2-capable cards.
For recent ISPs, software must detect OVERRUN conditions by
checking the SS_RESIDUAL_OVER bit during CS_COMPLETE handling.
Update the driver to perform this check, which is consistent with
what earlier firmwares did by explicitly cracking open the
FCP_RSP statuses and returning an CS_DATA_OVERRUN.

7c7f1f299b [SCSI] qla2xxx: Correct needless clean-up resets during shutdown.
There's no point in hitting the RISC with what will most
assuredly be an unsucessful reset of the RISC hardware if the
initial stop-firmware mailbox command fails with a time-out
status.  Instead, to avoid what could amount to a lengthy
stop-firmware/detect-failure/reset-risc loop, continue with
driver unloading and discard the stop-firmware requirement.

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

simple patch as I don't have hardware to test on.

d3f46f39b7 [SCSI] remove use_sg_chaining
With the sg table code, every SCSI driver is now either chain capable
or broken (or has sg_tablesize set so chaining is never activated), so
there's no need to have a check in the host template.

Also tidy up the code by moving the scatterlist size defines into the
SCSI includes and permit the last entry of the scatterlist pools not
to be a power of two.

df613b9607 [SCSI] qla2xxx: Add Fibre Channel Event (FCE) tracing support.
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.

285d0321d1 [SCSI] qla2xxx: Make driver (mostly) legacy I/O port free.
Recent ISPs need only the single MMIO BAR to manipulate HW
registers.  Unfortunately, ISP21xx, ISP22xx, ISP23xx, and ISP63xx
type cards still require the I/O mapped region to manipulate the
FLASH via the two HW flash-registers (flash_address and
flash_data).

94d6a2b328 [SCSI] qla2xxx: Fix issue where final flash-segment updates were falling into the slow-path write handler.
Original implementation would not use the burst-write mechanisms
for requests equal to OPTROM_BURST_DWORDS transfer dwords.

2c96d8d0c1 [SCSI] qla2xxx: Handle unaligned sector writes during NVRAM/VPD updates.
Since both NVRAM and VPD regions of the flash reside on unaligned
sector boundaries, during update, the driver must perform a
read-modify-write operation to the composite NVRAM/VPD region.
This affects ISP25xx type boards only.

a3a63d55a4 [SCSI] qla2xxx: Defer explicit interrupt-polling processing to init-time scenarios.
As the intermixing may cause issues where HCCR bits could be
cleared inappropriately during MSI/MSI-X interrupt handling.

9cb83c7529 [SCSI] add use_sg_chaining option to scsi_host_template
This option is true if a low-level driver can support sg
chaining. This will be removed eventually when all the drivers are
converted to support sg chaining. q->max_phys_segments is set to
SCSI_MAX_SG_SEGMENTS if false.
