This patch fixes an issue seen with an IBM 2145 (SVC) where, following an error
injection test which results in paths going offline, when they came
back online, the path would timeout the REPORT_LUNS issued during the
scan. This timeout situation continued until retries were expired, resulting in
falling back to a sequential LUN scan. Then, since the target responds
with PQ=1, PDT=0 for all possible LUNs, due to the way the sequential
LUN scan code works, we end up adding 512 LUNs for each target, when there
is really only a small handful of LUNs that are actually present.

This patch increases the timeout used on the REPORT_LUNS to 30 seconds.
This patch solves the issue of 512 non existent LUNs showing up after
this event.

Implemented JBOD map which will provide quick access for JBOD path and
also provide sequence number.  This will help hardware to fail command
to the FW in case of any sequence mismatch.

Fast Path I/O for JBOD will refer JBOD map (which has sequence number
per JBOD device) instead of RAID map.  Previously, the driver used RAID
map to get device handle for fast path I/O and this not have sequence
number information. Now, driver will use JBOD map instead.  As part of
error handling, if JBOD map is failed/not supported by firmware, driver
will continue using legacy behavior.

Now there will be three IO paths for JBOD (syspd):

 - JBOD map with sequence number (Fast Path)
 - RAID map without sequence number (Fast Path)
 - FW path via h/w exception queue deliberately setup devhandle
   0xFFFF (FW path).

Relevant data structures:

 - Driver send new DCMD MR_DCMD_SYSTEM_PD_MAP_GET_INFO for this purpose.
 - struct MR_PD_CFG_SEQ- This structure represent map of single physical
   device.
 - struct MR_PD_CFG_SEQ_NUM_SYNC- This structure represent whole JBOD
   map in general(size, count of sysPDs configured, struct MR_PD_CFG_SEQ
   of syspD with 0 index).
 - JBOD sequence map size is: sizeof(struct MR_PD_CFG_SEQ_NUM_SYNC)
   + (sizeof(struct MR_PD_CFG_SEQ) * (MAX_PHYSICAL_DEVICES - 1)) which
   is allocated while setting up JBOD map at driver load time.

The "compatible" matching algorithm used for looking up old-style
blacklist entries in a scsi_dev_info_list is buggy.  The core of the
algorithm looks like this:

		if (memcmp(devinfo->vendor, vendor,
			    min(max, strlen(devinfo->vendor))))
			/* not a match */

where max is the length of the device's vendor string after leading
spaces have been removed but trailing spaces have not.  Because of the
min() computation, either entry could be a proper substring of the
other and the code would still think that they match.

In the case originally reported, the device's vendor and product
strings were "Inateck " and "                ".  These matched against
the following entry in the global device list:

	{"", "Scanner", "1.80", BLIST_NOLUN}

because "" is a substring of "Inateck " and "" (the result of removing
leading spaces from the device's product string) is a substring of
"Scanner".  The mistaken match prevented the system from scanning and
finding the device's second Logical Unit.

This patch fixes the problem by making two changes.  First, the code
for leading-space removal is hoisted out of the loop.  (This means it
will sometimes run unnecessarily, but since a large percentage of all
lookups involve the "compatible" entries in global device list, this
should be an overall improvement.)  Second and more importantly, the
patch removes trailing spaces and adds a check to verify that the two
resulting strings are exactly the same length.  This prevents matches
where one entry is a proper substring of the other.

The proposed solution was approved by James Smart at Emulex and tested
on a UV2 machine with 6144 cores. With the fix, the LPFC module loads
with no unwanted effects on the system.

Currently the module parameter lpfc_sg_seg_count does not have effect
for sli3 devices.

In lpfc_sli_driver_resource_setup(), which is used for sli3, the code
writes the configured sg_seg_cnt into lpfc_template.sg_tablesize.
But lpfc_template is the template used for sli4 only. Thus the value should
correctly be written to lpfc_template_s3->sg_tablesize.

This patch is for kernel 4.1-rc5, but is tested with lpfc 10.2.405.26 only.
