The issue occur while deleting 60 virtual ports through the sys interface /sys/class/fc_vports/vport-X/vport_delete. It happen while in a mistake each request sent twice for the same vport. This interface is asynchronous, entering the delete request into a work queue, allowing more than one request to enter to the delete work queue. The result is a NULL pointer. The first request already delete the vport, while the second request got a pointer to the vport before the device destroyed. Re-create vport later cause system freeze. Solution: Check vport flags before entering the request to the work queue. [jejb: fixed int<->long problem on spinlock flags variable] Signed-off-by:

MS module did not invoke fdmi offline in all cases, call fdmi offline when ms module receives a port offline, so that fdmi offline is from one place in the ms module. Make changes to handle 10G speed in the conversion routine. Replaced the usage of bfa_adapter_attr_s struct with specific API's. 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.

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.
