tran_init_pkt() Entry Point

The tran_init_pkt(9E) entry point allocates and initializes a scsi_pkt(9S) structure and DMA resources for a target driver request.

The tran_init_pkt(9E) entry point is called when the target driver calls the SCSA function scsi_init_pkt(9F).

Each call of the tran_init_pkt(9E) entry point is a request to perform one or more of three possible services:

• Allocation and initialization of a scsi_pkt(9S) structure

• Allocation of DMA resources for data transfer

• Reallocation of DMA resources for the next portion of the data transfer
