The link can be put in LINKDOWN_DISABLE state either locally or via a MAD. However, the link-recovery code will take it out of that state as a side-effect of attempts to clear SerDes/XGXS issues. We add a flag to indicate "link is down on purpose, leave it alone." Signed-off-by: Michael Albaugh <michael.albaugh@qlogic.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>
