Introduce a link notification state machine to handle next incoming link events while the current event is being delivered to the driver. When the event has been processed by the driver, the link notification state machine will queue the next event (if there is any) to the driver. Signed-off-by:

Changed PCI VPD to incorporate specific OEM vendors. Added FCoE specific interrupt latency and delay params. Added some variables needed by FIP 2.0. Added some new logging and tracing definitions. Added reserved members to make the structures (IOC, IOCFC) 64bit aligned. Changed the module identifiers, as some files were moved. Signed-off-by:

Add support for faster IOC recovery after failure. Split bfa_ioc.c into three files: bfa_ioc.c: Common code shared between crossbow and catapult ASIC's. bfa_ioc_cb.c: Code specific to the crossbow, reg mapping and interrupt related routines. bfa_ioc_ct.c: Code specific to the catapult, reg mapping and interrupt related routines. Fix to make sure IOC reinitialize's properly on enable request - update the ioc_fwstate reg with BFI_IOC_FAIL on ioc disable mbox cmd timeout. Makefile changes to support the 2 newly added files bfa_ioc_cb.c and bfa_ioc_ct.c. Signed-off-by:

bfad.c & bfad_drv.h: * Created a kernel thread from pci_probe that does the bfad start operations after BFA init done on a firmware mismatch. * The kernel thread on a fw mismatch waits for an event from IOC call back and is woken up from bfa_cb_init() on BFA init success. * In normal cases of no firmware mismatch this thread is terminated in pci_probe. bfa_fcs_lport.c, fabric.c, fcs_lport.h & vport.c: * Split the lport init to attach time and init time code, so that proper config attributes are set after firmware mismatch. bfa_iocfc.c: * Handle an IOC timer issue, where the IOC timer would expire before the init completion and send Init fail event to the driver, however IOC init continues and completes successfully at the later stage. The bfa and driver were not handling this kind of deferred init completion. Signed-off-by: -

Brocade CNA currently supports only 190 vports (instead of 191), since there are only 192 unicast cam entries reserved for FCoE. Brocade CNA has a total of 256 unicast cam entries (192 FCoE + 64 LL) 192 cam entries = 1 burned in mac + 1 baseport FPMA mac + 190 vport FPMA macs. Made changes to the code to support only 190 vports. Signed-off-by:

Added a FCS function to be called during driver init, to set the FDMI Driver parameter. fdmi.c: Created a disabled state when fdmi is disabled. bfad.c: * Added fdmi_enable driver parameter. * Added support to call bfa_fcs_set_fdmi_param() to initialize fcs fdmi setting. Signed-off-by: -

Clear virtual links was not propagated upwards to bfa from fw. This resulted in HBA and switch being in an inconsistent state. So defined a new LPS event for clear virtual link on a vport, and also now clear virtual link on a baseport, is sent as a link down event from the fw. Signed-off-by:

RAID attributes uses scsi_is_sdev_device() to gate some SCSI specific checking code. This causes two problems. Firstly if SCSI == n just defining scsi_is_sdev_device() to return false might not be enough to prevent gcc from emitting the code (and thus referring to undefined symbols), so this needs surrounding with an ifdef. Secondly, using scsi_is_sdev_device() when SCSI is either y or m gives a subtle problem in the m case: raid_attrs must also be m to use the symbol. Do the usual Kconfig jiggery-pokery to fix this.

This uses the scatter-gather chaining feature of Smart Array controllers. 32 scatter-gather elements are embedded in the "command list", and the last element in the list may be marked as a "chain pointer", and point to an additional block of scatter gather elements. The precise number of scatter gather elements supported is dependent on the particular kind of Smart Array, and is determined at runtime by querying the hardware. Signed-off-by:

The intent of the scan thread was to allow a UNIT ATTENTION/LUN DATA CHANGED condition encountered in the interrupt handler to trigger a rescan of devices, which can't be done in interrupt context. However, we weren't able to get this to work, due to multiple such UNIT ATTENTION conditions arriving during the rescan, during updating of the SCSI mid layer, etc. There's no way to tell the devices, "stand still while I scan you!" Since it doesn't work, there's no point in having the thread, as the rescan triggered via ioctl or sysfs can be done without such a thread. Signed-off-by:

Adds support for resuming from suspend for IBM VFC devices. We may have lost an interrupt over the suspend, so we just kick the interrupt handler to process anything that is outstanding. We expect to find a transport event indicating we need to reestablish our CRQ. Signed-off-by:
