 * tag.
 *
 * A tag type of CBACK means that the the interrupt handler
 * takes the tag 'arg' in the work structure to be a callback
 * function pointer (see pmcs_cb_t). The callee is responsible
 * for freeing the work structure that has this tag.
 *
 * A tag type of WAIT means that the issuer of the work needs
 * be woken up from interrupt level when the command completes
 * (or times out). If work structure tag 'arg' is non-null,
 * up to 2*PMCS_QENTRY_SIZE bits of data from the Outbound Queue
 * entry may be copied to the area pointed to by 'arg'. This
 * allows issuers to get directly at the results of the command
