        src/sys/dev/ic: mpt_netbsd.c

Log Message:
Allow adapters with SAS/SATA or FC devices to use tagged queuing by the scsipi
layer.  Can improve write performance on SAS adapters under certain conditions
when the logical drive does not have write caching enabled.  Also need to
reserver a couple of slots for commands for the driver to use - stops the
adapter shortage messages.  Multiple commands can now cause QUEUE_FULL events,
so add that to the events handled, currently just ignoring it.  Changes
based on the thread
