New Revision: 260521
URL: http://svnweb.freebsd.org/changeset/base/260521
Log:
Remove not applicable PI_SDTR_ABLE and PI_WIDE_16 hba_inquiry flags to
make CAM to not try negotiate unsupported settings and suppress warnings.
While there, enable command queuing on pass-through devices, announced
in hba_inquiry, but disabled. Even though queue size is very small, It
seems working well enough.
