Nilesh Javali 906cbf3d2c qla4xxx: Export sysfs DDBs from DPC handler
Issue:
modprobe qla4xxx is killed by systemd due to timeout.

Solution:
The exporting of sysfs DDBs from qla4xxx_probe_adapter added delay of
approximately 15s due to which system-udevd killed the modprobe of the
driver. Added fix to export the sysfs DDBs from the DPC handler.

Tej Parkash 58e2bbe985 [SCSI] qla4xxx: Driver not able to collect minidump for ISP84xx
Issue:
minidump data collection fails as driver reports data mismatch

Fix:
When the driver encounters a new entry type that it cannot process,
it should just skip the entry and adjust the total buffer size by
subtracting the skipped bytes from it. This is to ensure that there
is no data mismatch because of the new entries.

Tej Parkash 61d9a2b614 [SCSI] qla4xxx: Fix pending IO completion in reset path before initiating chip reset
Issue:
Pending IO wait does not complete after triggering Graceful reset,
causing ack timeout and call traces.

Fix:
1. Reducing the IO command wait timeout before triggering reset,
   as logically also timeout should be less than reset timeout (10sec).
2. Moving the abort IO after chip reset, because only after
   chip reset, driver owns the IO otherwise it is with firmware and can
   still revert back with response.

was to store ram index of a sendtarget entry, but driver frees
sendtarget ram index as soon as firmware is done with discovery,

iscsi_session->discovery_parent_idx to store sendtarget flashnode index.

Vikas Chaudhary 5c19b92ae8 [SCSI] qla4xxx: Fix MBOX intr switching from polling to intr mode for ISP83XX
Issue:
Mailbox command timed out after switching from polling mode to interrupt mode.

Events:-
 1. Mailbox interrupts are disabled
 2. FW generates AEN and at same time driver enables Mailbox Interrupt
 3. Driver issues new mailbox to Firmware

In above case driver will not get AEN interrupts generated by FW in step #2 as
FW generated this AEN when interrupts are disabled. During the same time
driver enabled the mailbox interrupt, so driver will not poll for interrupt.
Driver will never process AENs generated in step #2 and issues new mailbox to
FW, but now FW is not able to post mailbox completion as AENs generated before
are not processed by driver.

Fix:
Enable Mailbox / AEN interrupts before initializing FW in case of ISP83XX.
This will make sure we process all Mailbox and AENs in interrupt mode.

Lalit Chandivade 4549415af6 [SCSI] qla4xxx: Do not add duplicate CHAP entry in FLASH
QLogic applications store the CHAP information in FLASH. During login,
authentication information is provided using an index into the CHAP region.

In order to support QLogic applications along with iscsiadm, updated the
LLD to not add duplicate CHAP entries in the CHAP region and preserve the
existing CHAP info in the CHAP region in FLASH.
This allows QLogic applications to pre-write the CHAP entries in the
CHAP region.

With iscsiadm, when the CHAP authentication information is sent to the LLD, the
LLD searches for the entry in CHAP region in FLASH, if exists then do not add.
If CHAP entry does not exist then add the CHAP entry in the CHAP region.
