New Revision: 300058
URL: https://svnweb.freebsd.org/changeset/base/300058
Log:
Make RQCS_PORT_LOGGED_OUT for ZOMBIE ports retriable.
It is normal for ZOMBIE ports to be logged out. This status is not really
an error until Gone Device Timeout expires, so make CAM retry after delay.
MFC after: 1 week
