Well the subscriptions in-deed succeeded and I was able to receive IPoIB broadcast multicast group creation/deletion traps as well, but the problem mentioned below (ie. non-blocking reads) started appearing. > main: Rather than hard coding SM LID to 0x12, there are ways to get this > dynamically. There are examples of how to do this. Sorry about this again. I realized it later that it is stupid to hard code it (eg. I could have got it from the ca[].port->sm_lid), will fix that eventually.
