/*
* Suggested Software Target Mode Command Handling structure.
*
* A note about terminology:
*
* MD stands for "Machine Dependent".
*
* This driver is structured in three layers: Outer MD, core, and inner MD.
* The latter also is bus dependent (i.e., is cognizant of PCI bus issues
* as well as platform issues).
*
*
* "Outer Layer" means "Other Module"
*
* Some additional module that actually implements SCSI target command
* policy is the recipient of incoming commands and the source of the
* disposition for them.
*
* The command structure below is one suggested possible MD command structure,
* but since the handling of thbis is entirely in the MD layer, there is
* no explicit or implicit requirement that it be used.
*
* The cd_private tag should be used by the MD layer to keep a free list
* of these structures. Code outside of this driver can then use this
* to identify it's own unit structures. That is, when not on the MD
* layer's freelist, the MD layer should shove into it the identifier
* that the outer layer has for it- passed in on an initial QIN_HBA_REG
* call (see below).
*
* The cd_hba tag is a tag that uniquely identifies the HBA this target
* mode command is coming from. The outer layer has to pass this back
* unchanged to avoid chaos.
*
* The cd_iid, cd_tgt, cd_lun and cd_port tags are used to identify the
* id of the initiator who sent us a command, the target claim to be, the
* lun on the target we claim to be, and the port instance (for multiple
* port host adapters) that this applies to (consider it an extra port
* parameter). The iid, tgt and lun values are deliberately chosen to be
* fat so that, for example, World Wide Names can be used instead of
* the units that the firmware uses (in the case where the MD
* layer maintains a port database, for example).
*
* The cd_tagtype field specifies what kind of command tag type, if
* any, has been sent with the command. Note that the Outer Layer
* still needs to pass the tag handle through unchanged even
* if the tag type is CD_UNTAGGED.
*
* The cd_cdb contains storage for the passed in command descriptor block.
* There is no need to define length as the callee should be able to
* figure this out.
*
* The tag cd_lflags are the flags set by the MD driver when it gets
* command incoming or when it needs to inform any outside entities
* that the last requested action failed.
*
* The tag cd_hflags should be set by any outside software to indicate
* the validity of sense and status fields (defined below) and to indicate
* the direction data is expected to move. It is an error to have both
* CDFH_DATA_IN and CDFH_DATA_OUT set.
*
* If the CDFH_STSVALID flag is set, the command should be completed (after
* sending any data and/or status). If CDFH_SNSVALID is set and the MD layer
* can also handle sending the associated sense data (either back with an
* FCP RESPONSE IU for Fibre Channel or otherwise automatically handling a
* REQUEST SENSE from the initator for this target/lun), the MD layer will
* set the CDFL_SENTSENSE flag on successful transmission of the sense data.
* It is an error for the CDFH_SNSVALID bit to be set and CDFH_STSVALID not
* to be set. It is an error for the CDFH_SNSVALID be set and the associated
* SCSI status (cd_scsi_status) not be set to CHECK CONDITON.
*
* The tag cd_data points to a data segment to either be filled or
* read from depending on the direction of data movement. The tag
* is undefined if no data direction is set. The MD layer and outer
* layers must agree on the meaning of cd_data and it is specifically
* not defined here.
*
* The tag cd_totlen is the total data amount expected to be moved
* over the life of the command. It may be set by the MD layer, possibly
* from the datalen field of an FCP CMND IU unit. If it shows up in the outer
* layers set to zero and the CDB indicates data should be moved, the outer
* layer should set it to the amount expected to be moved.
*
* The tag cd_resid should be the total residual of data not transferred.
* The outer layers need to set this at the begining of command processing
* to equal cd_totlen. As data is successfully moved, this value is decreased.
* At the end of a command, any nonzero residual indicates the number of bytes
* requested by the command but not moved.
*
* The tag cd_xfrlen is the length of the currently active data transfer.
* This allows several interations between any outside software and the
* MD layer to move data.
*
* The reason that total length and total residual have to be tracked
* is to keep track of relative offset.
*
* The tags cd_sense and cd_scsi_status are pretty obvious.
*
* The tag cd_error is to communicate between the MD layer and outer software
* the current error conditions.
*
* The tag cd_lreserved, cd_hreserved are scratch areas for use for the MD
* and outer layers respectively.

/*
* A word about the START/CONT/DONE/FIN dance:
*
* When the HBA is enabled for receiving commands, one may show up
* without notice. When that happens, the MD target mode driver
* gets a tmd_cmd_t, fills it with the info that just arrived, and
* calls the outer layer with a QOUT_TMD_START code and pointer to
* the tmd_cmd_t.
*
* The outer layer decodes the command, fetches data, prepares stuff,
* whatever, and starts by passing back the pointer with a QIN_TMD_CONT
* code which causes the MD target mode driver to generate CTIOs to
* satisfy whatever action needs to be taken. When those CTIOs complete,
* the MD target driver sends the pointer to the cmd_tmd_t back with
* a QOUT_TMD_DONE code. This repeats for as long as necessary. These
* may not be done in parallel- they are sequential operations.
*
* The outer layer signals it wants to end the command by settings within
* the tmd_cmd_t itself. When the final QIN_TMD_CONT is reported completed,
* the outer layer frees the tmd_cmd_t by sending the pointer to it
* back with a QIN_TMD_FIN code.
*
* The graph looks like:
*
* QOUT_TMD_START -> [ QIN_TMD_CONT -> QOUT_TMD_DONE ] * -> QIN_TMD_FIN.
