2014-05-19qla4xxx: Export sysfs DDBs from DPC handlerNilesh Javali3-6/+11
Issue: modprobe qla4xxx is killed by systemd due to timeout. Solution: The exporting of sysfs DDBs from qla4xxx_probe_adapter added delay of approximately 15s due to which system-udevd killed the modprobe of the driver. Added fix to export the sysfs DDBs from the DPC handler.

2014-05-19fnic: fnic Control Path Trace UtilityHiral Shah6-43/+637
Fnic Ctlr Path Trace utility is a tracing functionality built directly into fnic driver to trace the control path frames like discovery, FLOGI request/reply, PLOGI request/reply, link event etc. It will be one trace file for all fnics. It will help us to debug and resolve the discovery and initialization related issues in more convenient way. This trace information includes time stamp, Host Number, Frame type, Frame Length and Frame. By default,64 pages are allocated but we can change the number of allocated pages by module parameter fnic_fc_trace_max_page. Each entry is of 256 byte and available entries are depends on allocated number of pages. We can turn on or off the fnic control path trace functionality by module paramter fc_trace_enable and/or reset the trace contain by module paramter fc_trace_clear.

The command with abort queued state will never be queued next time for abort or termiantion. Fix restores the command state in above case.

2014-05-19fnic: NoFIP solicitation frame in NONFIP mode and changed IO Throttle countHiral Shah3-7/+4
This patch contains following three minor fixes. 1) During Probe, fnic was sending FIP solicitation in Non FIP mode which is not expected, setting the internal fip state to Non FIP mode explicitly, avoids sending FIP frame. 2) When target goes offline, all outstanding IOs belong to the target will be terminated by driver, If the termination count is high, then it influences firmware responsiveness. To improve the responsiveness, default IO throttle count is reduced to 256. 3) Accessing Virtual Fabric Id (vfid) and fc_map of Fibre-Channel Forwarder(FCF) is invalid in fnic driver when Clear Virtual Link(CVL) is received prior to receiving flogi reject from switch. As CVL clears all FCFs.
