bus resets are not issued by scsipi, it's up to the driver to decide to do
them or not. Fibre Channel adapters can chose to skip them.
For SCSI adapters I really think they should be there, it's the only way to
get the busses back to a sane state when something goes wrong.
And it looks like solaris 2.5 is doing it as well.
Other adapters on the bus should be able to cope with the bus reset, and
restart commands as appropriate.
