SM lid was incorrectly set to port lid. This is a regression from 2.6.17 -
after event, no traps are sent to the SM LID - they go to the
loopback interface instead, and are typicaly dropped there.
Should be set to sm_lid of port info response.

Roland, this fixes a serious regression from 2.6.17.
The bug was introduced by commit 12bbb2b7be7f5564952ebe0196623e97464b8ac5:
IB/mthca: Add client reregister event generation
I'm taking the fix into OFED 1.1 and I think it should go into 2.6.18 or
2.6.18.1.
