[SCSI] libosd: OSD2r05: on-the-wire changes for latest OSD2 revision 5.
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) Signed-off-by: Boaz Harrosh <bharrosh@panasas.com> Signed-off-by: James Bottomley <James.Bottomley@HansenPartnership.com>
