If an SRB is NULL but the handle is in range just drop the
command instead of also resetting the adapter. If the handle
is in range then the command was valid at some point and may
have been aborted. Resetting the adapter can lead to extended
recovery times in this case.

Whether htonl() or __constant_htonl() is used, if the argument
is a constant the conversion happens at compile time. Hence leave
out the __constant_ prefix for this and other endianness
conversion functions. This improves source code readability.

Through the qla target code, the qlt_send_term_exchange() routine
is used in various different places to cleanup an exchange. For the
case of IOCB request queue is full, the exchange is left unhandled/
dangling. Existing code does not have re-try logic to cleanup the
exchange. This patch add retry logic to cleanup the exchange before
letting new commands through.
For the case of FW running out of exchanges, driver need to reply
SAM_STAT_BUSY to the initiators. This patch add a pending queue
for the busy reply in case IOCB queue is unable to handle the cmd.

Limiting which port update events will allow the driver to kick off a
name server scan has been problematic in some corner cases so remove the
restriction and restore the previous semantic. Also move the link

Attempting to do any logins from the SCSI reset handler can lead to a deadlock
scenario if a rport times out and the FC transport layer. Move doing any port
logins to the DPC thread so as not to impede the progress of the SCSI error

If we become disconnected from the PCI bus/PCIe fabric, there can be long delays
in register reads which can cause erroneous decisions to be made and cause a
soft lockup if a lock is held too long. As a preventative measure, check for a
disconnection (register reads that return -1) and then disable the board if we
find ourselves in this condition. For now, check in our interrupt handlers and
the per adapter one second timer.

If an invalid IOCB is returned on the response queue then the index into the
request queue map could be invalid and could return to us a bogus value. This
could cause us to try to deference an invalid pointer and cause an exception.
If we encounter this condition, simply return as no context can be established
for this response.
