New Revision: 184662
URL: http://svn.freebsd.org/changeset/base/184662

Log:
  MFC: r184379
  
  Supply a valid Connect ID when issuing XPT_DEV_MATCH, which
  according to my reading of the CAM draft is mandatory for
  all CCB function calls and enforced by xptioctl() since at
  least r168752. Previously we happened to use 0 as the Path
  ID, causing the XPT_DEV_MATCH call to fail if there's no
  SCSI bus 0. Basically the same bug was also fixed the same
  way for camcontrol(8) as part of r126514.
