in caller's error handling path.

There exists a race condition between CQ doorbell unmap and IO completion path
that arms the CQ which causes a NULL dereference. Protect the ctx_base with
cq_lock to avoid this. Also, wait for the CQ doorbell to be successfully mapped
before arming the CQ.
Also, do not count uncolicited CQ completions for free_sqes.

During the unsolicited LOGO processing, the session is uploaded and offloaded
after the relogin is complete. In between any new IOs are errored back as the
upload completion flag is set. Upon exhausting the retry count, the application
fails the IOs. Return target busy for all the cases when session is not ready.

When NPIV ports are created/deleted rapidly there is a race condition between
bnx2fc_vport_destroy() from sysfs and bnx2fc_flogi_resp(), which could try to
delete the NPIV port from the list twice. Fix is to loop through the list of
NPIV ports to find a match, and only when it exists remove it.

from fault reset thread, which has been called from work thread
context after each specific interval. If doorbell value is 0xFFFFFFFF,
it will be considered as IOC is non-operational and marked as dead

This fix:
- Disables app tag peeking; correct tag check will be added when the
SCSI API is available.
- Always derive ref_tag from scsi_get_lba()
- Removes incorrect swap of FCP_LUN in FCP_CMND
- Moves app-tag error check before ref-tag check. The reason being,
currently there is no interface in SCSI to retrieve the app-tag
for protection I/Os, so driver puts zero for app-tag in the
firmware interface, but requests not to validate it, but when a
ref-tag error is detected by firmware, it would put
expected/actual tags for all the protection tags (guard/app/ref).
As driver checks for app tag error first, a ref-tag error is
incorrectly flagged as app-tag error.
- Convert HBA specific checks to capability based.

If a physical device exposed to the OS by hpsa
is replaced (e.g. one hot plug tape drive is replaced
by another, or a tape drive is placed into "OBDR" mode
in which it acts like a CD-ROM device) and a rescan is
initiated, the replaced device will be added to the
SCSI midlayer with target and lun numbers set to -1.
After that, a panic is likely to ensue. When a physical
device is replaced, the lun and target number should be
preserved.

Hardware allows both an outstanding number commands and a timeout value
(whichever occurs first) as a gate to the next interrupt generation. This
scheme at completion time looks at the remaining number of outstanding tasks
and sets the timeout to maximize small transaction operation. If transactions
are large (take more than a few 10s of microseconds to complete) then
performance is not interrupt processing bound, so the small timeouts this
scheme generates are overridden by the time it takes for a completion to
arrive.

Need the following workaround in the driver for interoperability with
the older Intel SSD drives and any other SATA drive that may exhibit the
same behavior. This is a corner case where SCU speed is limited to
either 3G or 1.5G and the drive has a period of DC idle when it switches
speed during SATA speed negotiation. Workaround :change PHYTOV[31:24]
from 0x36 to 0x3B.

The unsolicited frame control infrastructure requires a table of dma
addresses for the hardware to lookup the frame buffer location by an
index. The hardware expects the elements of this table to be 64-bit
quantities, so we cannot reference these elements as dma_addr_t. All
unsolicited frame protocols are affected, particularly SATA-PIO and SMP
which prevented direct-attached SATA drives and expander-attached drives
to not be discovered.
