This is a regression from 2.6.17 -- after a PortInfo MAD is received, no traps are sent to the SM LID. The traps go to the loopback interface instead, and are dropped there. The SM LID should be taken from the sm_lid of the PortInfo response. The bug was introduced by commit 12bbb2b7be7f5564952ebe0196623e97464b8ac5: IB/mthca: Add client reregister event generation Signed-off-by: Jack Morgenstein Signed-off-by: Michael S.
