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.Signed-off-by: Nilesh Javali

Issue:
minidump data collection fails as driver reports data mismatchFix:
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.Signed-off-by: Tej Parkash

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.Signed-off-by: Tej Parkash

Earlier logic for driver created iscsi_session->discovery_parent_idx
was to store ram index of a sendtarget entry, but driver frees
sendtarget ram index as soon as firmware is done with discovery,
which is available for further use. So changing the logic to point
iscsi_session->discovery_parent_idx to store sendtarget flashnode index.Signed-off-by: Manish Rangankar

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 FirmwareIn 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.Signed-off-by: Vikas Chaudhary

In qla4xxx_ep_connect(), qla_ep->dst_addr and dst_addr are type
struct sockaddr. We are copying sizeof(struct sockaddr_in6) bytes
from dst_addr to qla_ep->dst_addr which is 12 bytes larger. This
will cause memory corruption. So we change qla_ep->dst_addr to
struct sockaddr_storage which is of 128 byte, large enough to
hold sizeof(struct sockaddr_in6).Signed-off-by: Manish Rangankar
