[openib-general] OpenSM 1.1.0 and Multicast Registration

[Hal Rosenstock]

Hi,

I have observed 2 cases of issues with multicast reregistration with
OpenSM 1.1.0:

1. In the case where the initial sweep is not completed, when 

Sep 14 14:14:50 964956 [B5EB7AC0] -> __osm_sa_mad_ctrl_rcv_callback: 9 QP1 MADs received.
Sep 14 14:14:50 998694 [B5EB7AC0] -> __osm_sa_mad_ctrl_rcv_callback: Received an SA mad while SM in first sweep. Mad ignored.

It seems to me that OpenSM shouldn't send client reregister until after
first sweep as it is not prepared to handle any SA requests until then.

2. Delete and then create same group: delete is responded to but create
isn't. (Prior to "[PATCH] IPoIB: Fix SA client retransmission strategy"
which paves over this).
