[openib-general] IB mcast question

[Roland Dreier]

    Steve> So is this replicating done in the mthca hca?

Yes, it should be.  There may be a bug in the mthca kernel multicast
code for handling multiple QPs attached to the same group.

    Steve> Since one app is getting the mcast packet, can I assume the
    Steve> opensm code is doing the right thing switch/port wise?

Yep.

    Steve> Should the SM get join requests for both applications that
    Steve> join the group on the same host?  Or only the first one?

No there should only be one join request for a given port.
