Vijaya Mohan Guvva 22a08538dc [SCSI] bfa: Fix crash when symb name set for offline vport
This patch fixes a crash when tried setting symbolic name for an offline
vport through sysfs. Crash is due to uninitialized pointer lport->ns,
which gets initialized only on linkup (port online).

Jingoo Han 08b7e10716 SCSI: remove unnecessary pci_set_drvdata()
Since commit 0998d06310
(device-core: Ensure drvdata = NULL when no driver is bound),
the driver core clears the driver data to NULL after device_release
or on probe failure. Thus, it is not needed to manually clear the
device driver data to NULL.

D-Port is a new port type created with the intention of running link
level diagnostic tests like loopback, traffic test. In static D-port
mode, user configures the port to D-port mode and starts the test, but
in dynamic D-port, once the Brocade switch port is configured to
D-port, it will reject the regular FLOGI from HBA with reason that it is
in D-port mode. So based on the reason code HBA port will turn itself into
D-port and start diagnostic test.

Vijay Mohan Guvva 111ecbe426 [SCSI] bfa: fix faulty handling of events in lps sm
When a switch disable/enable or a reboot is done, the HBA port gets an
offline and a subsequent online notification. When the port comes up a
link up notification is sent to bfa from the firmware. The bfa then send
an FLOGI to the firmware which is sent out on the wire.
The switch port meanwhile goes offline (presumably for diagnostics)
which causes the switch not to respond to the FLOGI.
The link down notification is sent to the HBA driver. However owing to a
bug in the lps state machine handling the lps state machine does not
move to sm_init state (it remains in sm_login state and send a login
complete message to fcs). This results in a zero PID assignment as the
login is not really complete.

This fix is to correctly handle the events in lps state machine.

Krishna Gudipati 7d0ecef383 [SCSI] bfa: Firmware image naming convention update
- Modified the firmware naming convention to contain the
  firmware image version (3.1.0.0).
- The new convention is <firmware-image>-<firmware-version>.bin
- The change will enforce loading only compatible firmware with this driver
  and also avoid over-writing the old firmware image in-order to load new
  version driver as the firmware names used to be the same.

Krishna Gudipati 04ea657562 [SCSI] bfa: Fabric Assigned Address implementation fix
- Made changes such that once the PWWN is acquired from the fabric through FAA,
  and if the FAPWWN configuration is modified on the switch side, driver should
  show relevant information to the user.
- Added logic to cache the reason code when the given port is disabled implicitl
  due to FAA error condition.
- If the port is disabled, while sending SCN to upper layer, update the
  reason code appropriately. With this, BFA FC port state machine will enter
  into faa_err_config state. This state will be shown to the user.

  3. No auto topology detection. User has to manually set the
