[SCSI] mpt2sas: fix driver version inconsistency

    [SCSI] mpt2sas : bump driver version to 01.100.02.00
 
The MPT2SAS_MAJOR_VERSION didn't get bumped from 00 to 01 so
applications will see it incorrectly as 00.100.02.00 driver instead of
01.100.02.00.  Fix by making MPT2SAS_MAJOR_VERSION match the major
number in MPT2SAS_DRIVER_VERSION

The same can happen for iscsi when transitioning from logged in
to failed and blocking the sdevs.

This patch converts iscsi and fc's transitions back to use DID_IMM_RETRY
instead of DID_TRANSPORT_DISRUPTED which has a limited number of retries
that we do not want to use for handling this race.

[SCSI] initialize max_target_blocked in scsi_alloc_target

2009-05-14T21:17:46+00:00

This patch initializes the max_target_blocked field of a scsi target
structure so that a queuecommand return value of
SCSI_MLQUEUE_TARGET_BUSY will actually result in having the
scsi_queue_insert blocking the device queue before requeuing the
command and running the queue.  Otherwise, can and does cause livelock
on single CPU configurations if/when open-iSCSI software initiator's
command PDU window fills.

[SCSI] libosd: OSD2r05: on-the-wire changes for latest OSD2 revision 5.

2009-04-27T16:05:49+00:00

OSC's OSD2 target: [git clone git://git.open-osd.org/osc-osd/ master]
(Initiator code prior to this patch must use: "git checkout CDB_VER_OSD2r01"
 in the target tree above)

This is a summery of the wire changes:

 * OSDv2_ADDITIONAL_CDB_LENGTH == 192 => 228 (Total CDB is now 236 bytes)
 * Attributes List Element Header grew, so attribute values are 8 bytes
   aligned.
 * Cryptographic keys and signatures are 20 => 32
 * Few new definitions.

(Still missing new standard definitions attribute values, these do not change
 wire format and will be added later when needed)

[SCSI] libosd: OSD2r05: OSD_CRYPTO_KEYID_SIZE will grow 20 => 32 bytes

2009-04-27T16:05:41+00:00

In OSD2r04 draft, cryptographic key size changed to 32 bytes from
OSD1's 20 bytes. This causes a couple of on-the-wire structures
to change, including the CDB.

In this patch the OSD1/OSD2 handling is separated out in regard
to affected structures, but on-the-wire is still the same. All
on the wire changes will be submitted in one patch for bisect-ability.

[SCSI] libosd: OSD2r05: Prepare for rev5 attribute list changes

2009-04-27T16:05:40+00:00

In OSD2r05 draft each attribute list element header was changed
so attribute-value would be 8 bytes aligned. In OSD2r01-r04
it was aligned on 2 bytes. (This is because in OSD2r01 the complete
element was 8 bytes padded at end but the header was not adjusted
and caused permanent miss-alignment.)

OSD1 elements are not padded and might be or might not be aligned.
OSD1 is still supported.

In this code we do all the code re-factoring to separate OSD1/OSD2
differences but do not change actual wire format. All wire format
changes will happen in one patch later, for bisect-ability.
