Log Message:
fix issues when reading variable block sized tapes.
symptoms:
generic HBA error on console when reading
with a larger blocksize. blocks read
are padded to requested block size with
a 5a... a5... pattern.
problems fixed:
- controller scsi_status values did not match
the ones used by the spsipi layer.
a mapping function was introduced.
- when experiencing an underrun (read 64k and
get a 63k block) the controller posted
not a SUCCESS status but CHECK status. handle
that like SUCCESS adjusting xs->resid and set
XS_SENSE.
now the correct data amount is returned and
nothing is 'added' and no 'generic HBA error'
occurs.
- make decisions using variables and constants
from the controller domain.
