From b3d5cb2f2067b30da53aa67e42fdd733030fb411 Mon Sep 17 00:00:00 2001 From: Mike Marciniszyn Date: Mon, 10 Jan 2011 17:42:20 -0800 Subject: IB/qib: Handle transitions from ACTIVE_DEFERRED to ACTIVE better When the link transitions from ACTIVE_DEFERRED to ACTIVE, the driver only sees the ACTIVE state. With this change, it will check whether the state was already ACTIVE and if so, it will not generated IB events and will not clear symbol error counts.
