Be careful of that. The original PDC hardware for ADMA still had

That is part of the ADMA spec - but in that case, how come the
pdc_adma.c driver sets the dma_boundary in the SCSI host template to

Ah, you are correct. My memory is fading of such things.
The PDC parts are good for 2^34 transfer sizes (bytes).
