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.

- 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.

- Introduced support for D-Port which is a new port mode during which
link level diagnostics can be run.
- Provided mechanism to dynamically configure D-Port and initiate diagnostic
tests to isolate any link level issues.
- In D-Port mode, the HBA port does not participate in fabric or login to the
remote device or run data traffic.
- Diagnostic tests include running various loopback tests in conjunction with
the attached device.

- Add private loop topology support at 2G/4G/8G speeds with following
limitations
1. No support for multiple initiators in the loop
2. No public loop support. If attached to a loop with an FL_Port,
device continues to work as a private NL_Port in the loop
3. No auto topology detection. User has to manually set the
configured topology to loop if attaching to loop.
- When loop topology is configured, enabling FC port features
QoS/Trunk/TRL are not allowed and vice versa.

- Added logic to generate a FCCT Reject indicating unsupported command,

if a PRLI response is a reject with a reason Command Not Supported.
- Updated the FDMI Supported/Current speeds.
- Added logic to wait for the response from the firmware before sending
ACC to PLOGI and transitioning to subsequent states - while processing an
Incoming PLOGI in online state.
- Added a wait state in the fcs_vport state machine - For case where
FDISC is in progress and we get a vport delete request we wait for
fdisc response and will transition to the appropriate state based on

Bug Fixes:
- Removed check for ignoring plogi from initiator in switched fabric mode.
- The ABTS for PLOGI is going out few millisecs earlier due to FW
timer calibration (around 300 miilisecs earlier). So there is a
window if an accept comes during this time HBA would have initiated
an ABORT.
- Added 1 to FC_ELS_TOV for compensating for FW timer.
