From 12bbb2b7be7f5564952ebe0196623e97464b8ac5 Mon Sep 17 00:00:00 2001 From: Leonid Arsh Date: Sat, 17 Jun 2006 20:37:36 -0700 Subject: [PATCH] IB/mthca: Add client reregister event generation Change the mthca snoop of MADs that set PortInfo to check if the SM has set the client reregister bit, and if it has, generate a client reregister event. If the bit is not set, just generate a LID change event as usual.
