A user specifies the values for the MCMemberRecord when they issue the join request, so the user controls all values. There is a call (ib_sa_get_mcmember_rec) that can be used to lookup an existing record, or obtain some default values for an MCMemberRecord if the user doesn't care what they are. I believe that the default values are the hard-coded values that you're referring to. The rdma_cm calls ib_sa_get_mcmember_rec() to lookup the broadcast group used by ipoib. It uses the returned MCMemberRecord as a template for creating new groups. The hard-coded values are only there for users that want to create a group, and don't care anything about its values. I hope this makes sense. - Sean _______________________________________________ openib-general mailing list [email protected] http://openib.org/mailman/listinfo/openib-general To unsubscribe, please visit http://openib.org/mailman/listinfo/openib-general
