As I expected, the apple scsi is doing something funny. I guess I will
have to repack the s/g list before sending down to scsi.
The Apple SCSI isn't creating the s/g list ... it's your driver which
created it, including the in-memory layout. You can just create it
more intelligently. :)
SBP-2 supports sending page table requests, which are basically
scatter/gather lists. The most convenient and fastest way is to just
use the same sizes as specified by apple (which is I suppose a direct
map from the SCSI s/g on the apple side). The alternative is to either
coalesce the s/g entries into one buffer, or pack them up together and
do a very annoying mapping from the new s/g arrangement to the old one
so that I write back across the bus where the apple expects.
