When qla2xxx and Target Core gets out of sync during command cleanup, qla2xxx
will not free command until it is out of firmware's hand and Target Core has
called the release on the command.
This patch adds synchronization using cmd_lock and release flag. If the
release flag is set, then qla2xxx will free up the command using
qlt_free_cmd() otherwise transport_generic_free_cmd() will be responsible for
relase of the command.

Add ability to allow each physical port to control operating mode. Current
code forces all ports to behave in one mode (i.e. initiator, target or
dual). This patch allows user to select the operating mode for each port.
- Driver must be loaded in dual mode to allow resource allocation
modprobe qla2xxx qlini_mode=dual
- In addition user can make adjustment to exchange resources using following
command
echo 1024 > /sys/class/scsi_host/host<x>/ql2xiniexchg
echo 1024 > /sys/class/scsi_host/host<x>/ql2xexchoffld
- trigger mode change and new setting of ql2xexchoffld|ql2xiniexchg
echo [<value>] > /sys/class/scsi_host/host<x>/qlini_mode
where, value can be one of following
- enabled
- disabled
- dual
- exclusive

Add sysfs support to control zio6 interrupt threshold. Using this sysfs hook
user can set when to generate interrupts. This value will be used to tell
firmware to generate interrupt at a certain interval. If the number of
exchanges/commands fall below defined setting, then the interrupt will be
generated immediately by the firmware.
By default ZIO6 will coalesce interrupts to a specified interval
regardless of low traffic or high traffic.

Following changes are added by this patch
- Prevent ABTS Response from getting in front of Termination of exchange.
Firmware requires driver to cleanup exchanges before ABTS response can be
sent. This reduces ABTS response error which triggers extra command
re-termination and re-sending of ABTS response.
- Add bits in driver and tracks CTIO/ATIO attribute bits for proper command
Termination. A copy of the ATTR bits will be kept in the ABTS task
management command as a back up copy, if an ABTS response encounters an
error.

ABTS error completion can trigger an exchange cleanup from the driver and
another ABTS response will be generated. This retry of ABTS response can
cause loop between driver trying to send ABTS and firmware returning error.
This patch fixes this issue by adding logic to check for unresolved exchanges
and clean up before ABTS is retried. This patch also addes the fix to use the
same qpair as the ABTS completion for the terminatation of exchange as well as
retry of ABTS response.

Currently, the rport registration is being called from a single work element
that is used to process QLA internal "work_list". This work_list is meant for
quick and simple task (ie no sleep). The Rport registration process sometime
can be delayed by upper layer. This causes back pressure with the internal
queue where other jobs are unable to move forward.
This patch will schedule the registration process with a new work element
(fc_port.reg_work). While the RPort is being registered, the current state of
the fcport will not move forward until the registration is done. If the state
of the fabric has changed, a new field/next_disc_state will record the next
action on whether to 'DELETE' or 'Reverify the session/ADISC'.
