Author: mav Date: Sun Feb 26 19:23:03 2017 New Revision: 314307 URL: https://svnweb.freebsd.org/changeset/base/314307 Log: Add support for SIMs without autosense. If we asked to send sense data by setting CAM_SEND_SENSE, but SIM didn't confirm transmission by setting CAM_SENT_SENSE, assume it was not sent. Queue the I/O back to CTL for later REQUEST SENSE with ctl_queue_sense(). This is needed for error reporting on SPI HBAs like ahc(4)/ahd(4).
