* [SCSI] bfa: io tag handling and minor bug fix.Krishna Gudipati2010-12-21
| | | | | | | | | | | | | | | | | | | | | Fix iotag handling: 1) Update and check io tag for retry case. 2) Clearing upper 3 bits in io tag when an IO completes. The 3 upper bits in io tags are used for counting FCP exchange retry. Un-cleared bits will cause firmware to access invalid memory when the same io tag is used for an IO to a target that doesn't support FCP exchange retry. 3) Only check the effective bits when validating an iotag. Other minor fixes: 1) Added trace to get FC header type with assert of unhandled packet received. Ignore the type FC_TYPE_FC_FSS (FC_XS). 2) Fixed the adapter info display check - to check for fcmode flag even.

* [SCSI] bfa: direct attach mode fix.Krishna Gudipati2010-12-21

* [SCSI] bfa: IOC auto recovery fix.Krishna Gudipati2010-12-21
| | | | | | | | | | - Made IOC auto_recovery synchronized and not timer based. - Only one PCI function will attempt to recover and reinitialize the ASIC on a failure, after all the active PCI fns acknowledge the IOC failure.

* [SCSI] bfa: Store port configuration in flash for persistency.Krishna Gudipati2010-12-21
| | | | | | | | | | | | When the bfa driver is loaded a flogi is sent without the knowledge of trunking configuration. This normal flogi causes the switch ports which had trunking enabled to go to persistent offline. Solution is to store the port configuration (which has trunking info) in the flash for persistency. The firmware will read this configuration when the very first fcport enable is received.

* [SCSI] bfa: IOC fwtrace save logic & state machine fixes.Krishna Gudipati2010-12-21
| | | | | | | | | | | - Move fw trace save logic to bfa_ioc_sm_fail_entry(), so that fw trace is saved irrespective of the cause of the failure. - Make bfa_ioc_sm_fail() a failure parking state. - Rename bfa_ioc_sm_initfail() to a more appropriate bfa_ioc_sm_fail_retry() as it is no longer a parking state.

* [SCSI] bfa: scatter gather processing changeMaggie Zhang2010-12-21
| | | | | | | | | | | | | | | | | Modified scatter gather processing to use the kernel provided scsi_for_each_sg() macro. 1) Instead of allocating and setting up sgpg in bfa_ioim_sge_setup(), we only do allocation. As a result, we remove bfa_ioim_sgpg_setup() and rename bfa_ioim_sge_setup() to bfa_ioim_sgpg_alloc(). 2) bfa_ioim_send_ioreq() call scsi_for_each_sg() to handle both inline and sgpg setup.

* [SCSI] zfcp: Add allow_lun_scan module parameterChristof Schmitt2010-12-21
| | | | | | | | | | | The zfcpdump tool requires a method to attach exactly one LUN. The easiest way to achieve this is to add a new zfcp module parameter.

| | | | | | | | | | | | | | | The tracing environment of the zfcp LLD has become very bulky and hard to maintain. Small changes involve a large modification process which is error-prone and not effective. This patch is the first of a set to redesign the zfcp tracing to a more straight-forward and easy to extend scheme. It removes all interpretation and visualization parts and focuses on bare logging of the information. This patch deals with all trace records of the zfcp error recovery.

* [SCSI] libfc: fix statistics for FCP input/output megabytesJoe Eykholt2010-12-21
| | | | | | | | | | | | | | | | | | | | | | The statistics for InputMegabytes and OutputMegabytes are misnamed. They're accumulating bytes, not megabytes. The statistic returned via /sys must be in megabytes, however, which is what the HBA-API wants. The FCP code needs to accumulate it in bytes and then divide by 1,000,000 (not 2^20) before it presented via sysfs. This affects fcoe.ko only, not fnic. The fnic driver correctly by accumulating bytes and then converts to megabytes. I checked that libhbalinux is using the /sys file directly without conversion. BTW, qla2xxx does divide by 2^20, which I'm not fixing here.

| | | | | | | | | | | | | | | | | | When there are several FCFs to choose from, the one most likely to accept a FLOGI on certian switches is the one that last answered a multicast solicit. So, when receiving an advertisement, move the FCF to the front of the list so that it gets chosen first among those with the same priority. Without this, more FLOGIs need to be sent in a test with multiple FCFs and a switch in NPV mode, but it still eventually finds one that accepts the FLOGI.
