From 4330e4dad780467d930b394b5119c0218a1e2dbe Mon Sep 17 00:00:00 2001 From: Michael Albaugh Date: Wed, 16 Apr 2008 21:09:26 -0700 Subject: IB/ipath: Prevent link-recovery code from negating admin disable 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."
