What is the purpose of the scsipi_minphys() function pointer in the
scsipi_adapter struct?
I thought it could be used to give an upper bound on the amount of
data that is given to the scsipi_cmd() function.
This interpretation is obviously wrong, because I use the minphys
function to limit the bp->b_bcount to 16K, but scsipi_cmd() is happily
given larger chunks to transfer despite this.
If this is not the way to limit the size, how can I limit it?  If I can't limit
it, what is the minimum that a driver has to be able to handle?
