SCSI: bfa: Chinook quad port 16G FC HBA claim issue

2014-02-06T19:05:48+00:00

commit dcaf9aed995c2b2a49fb86bbbcfa2f92c797ab5d upstream.

Bfa driver crash is observed while pushing the firmware on to chinook
quad port card due to uninitialized bfi_image_ct2 access which gets
initialized only for CT2 ASIC based cards after request_firmware().
For quard port chinook (CT2 ASIC based), bfi_image_ct2 is not getting
initialized as there is no check for chinook PCI device ID before
request_firmware and instead bfi_image_cb is initialized as it is the
default case for card type check.

This patch includes changes to read the right firmware for quad port chinook.

[SCSI] bfa: BSG and User interface fixes.

2012-03-28T08:57:58+00:00

Made changes to set the rport maxfrsize param to use a value that is
equal to or less than the Buffer-to-Buffer Receive Data_Field size
specified in the Common Service Parameters.
Increased the diag memtest timeout for the Brocade-1860 adapters.
Made changes to enable valid port speed configuration check for all adapters.
Made changes to increase the max hw segments in a request, in order to
support larger data transfers from user space.

[SCSI] bfa: Fix to avoid vport delete hang on request queue full scenario.

2012-03-28T08:57:09+00:00

Fixed the LPS (Logical Port Services) state machine to send a
FDISC/FLOGI to the FW from the request queue wait state, when
there is space available again on the request queue.
Made changes to free the vport on LOGO/cleanup complete instead
of free'ing it from vport_delete_handler in the module unload scenario.

[SCSI] bfa: Move service parameter programming logic into firmware.

2012-03-28T08:56:19+00:00

Programming of the service parameters Tx credits etc., is now done in firmware.
Remove the logic of sending the service parameters to firmware from driver.

[SCSI] bfa: Revised Fabric Assigned Address(FAA) feature implementation.

2012-03-28T08:55:22+00:00

Made changes to the Fabric Assigned Address(FAA) feature implementation.
Introduced the IOCFC state machine, which now handles the FAA logic,
IOC and BFA sub-modules enablement.
Removed un-wanted FAA enable/disable routines; FAA is enabled by default.

ahead with flash controller pause/resume logic.
Made changes to avoid clearing off the interrupts during the initial
pll initialization.

[SCSI] bfa: Serialize the IOC hw semaphore unlock logic.

2012-03-28T08:53:45+00:00

Made changes to ensure only the function that comes first will execute
the IOC hw semaphore unlock logic.
Used IOC init sem register to serialize execution of the unlock logic.
