* scsi: Fix up files implicitly depending on module.h inclusionPaul Gortmaker2011-11-013-0/+3

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Miscellanous logic and interface fixes - Fix lpfc_init_vfi_cmpl to check the interface type for interface type 0 before parsing the results. - Cast uint32_t values that are multiplied to uint64_t before the multiplication. - Instead of "break" statement when PCI read returned error, use the goto statement to the end of the routine after setting return value - moved the msleep(10) to the beginning of the wait loop for checking the SLIPort_Status register - Added the code to follow the existing wait for SLIPort_Status register RDY, ERR, and RN bits to be set by the port before proceeding to perform PCI function reset. - Do not override ulpCt_h and ulpCt_l for SLI 4 ports. - For vport delete, call lpfc_nlp_put when the vport's vpi state is not marked with VPI_REGISTERED. - Added missed fields into the driver's Controller Attributes Structure - Changed ringing EQ/CQ/RQ doorbell register to be dependent on the size of the queue. - Return -EACCES in issue_reset if cfg_enable_hba_reset is zero. - Added new logging flag LOG_FCP_UNDER 0x00040000 to qualify underrun logging. - Add a check in the fabric name display routine to display 0 if the port state is <= FLOGI. - Add a check to the switch statement in lpfc_decode_firmware_rev to check for an 'X'.

| | | | | | | | | | | | | | | | | | | | | | | | Fix SYSFS interface issues. - In the lpfc_sli4_pdev_status_reg_wait() routine, after initial 100ms delay following write to PHYSDEV_CONTROL register for the firmware reaction, check the RN bit and ERR bit of the SLIPORT_STATUS register. If none of them became 1, the previous PHYSDEV_CONTROL register should be considered failed due to lack of privilege and error for no permission should be returned immediately without getting into the wait for RDY bits on the SLIPORT_STATUS register. - Remove the driver check on dev->is_physfn before proceed to perform the PHYSDEV_CONTROL register write, and let the PCI function's privilege setting and driver handling of PHYSDEV_CONTROL register write failure to handle the reset-ability through the SLI port. - Added key to ctlreg_write to prevent unauthorized or unexpected write to the control register. - Change return to EACCES for sysfs access that are failed because hba_reset is disabled.

| | | | | | | | | | | | | | | | | | | | | | | Fix HBA initialization issues - Swap all values that come from the firmware image on little endian systems. Created a new bf_get_be macro that does the same as the bf_get_le macro but for big endian data instead of little endian data. - Moved the incrementing of temp_offset after the copy fixed the write object loop to use temp_offset to figure out where the end of the image is instead of offset. - Added the necessary codes for properly bringing the driver instance offline and then trying to bring the port back online with the PCI function IP reset. If it fails to bring the SLI port back online, it will fall through to bringing the SLI port to HBA error offline. - Add a call in the probe_one_s3 and probe_one_s4 routines to get the Modeldesc - Change OCe50100 to OCe15100 - Made the error log also include the PCI BAR bitmap returned from kernel call pci_select_bars().

| | | | | | | | | | | | | | | | | | | | | | | | | | | Miscellaneous Fixes and Corrections - Remove the memset in the lpfc_sli4_remove_rpi_hdrs call. - Correct swapping of SGE word 2 relative to offset value - Reorganize CQ and EQ usage to comply with SLI4 Specification. - Expand the driver to check the rn bit. Only detect an error if the error bit is set and the RN bit is NOT set. - If mailbox completion code is not success AND the mailbox status is success, then and only then will the driver overwrite the mailbox status. - When driver initializing device, if the device is on a PCIe bus, set PCI's "needs fundamental reset" bit so that EEH uses fundamental reset instead of hot reset for recovery. - Prevent driver from using new WWN when changed in firmware (until driver reload) - When HBA reports maximum SGE size > 0xffffffff (infinite), override with 0x80000000. - Fixed potential missed SLI4 device initialization failure conditions. - Added 100ms delay before driver action following IF_TYPE_2 function reset. - Reverted patch to UNREG/REG on PLOGI to mapped/unmapped node. - Add a check for the CVL received flag in the fcf inuse routine to avoid unregistering the fcf if Devloss fires before Delay discover timer fires.
