[ofa-general] Queue pair state for multicast group attachment

[Stefan Roscher]

Hi,

during testing with ib_diag tools (ib_send_lat/bw) we noticed some problems by using multicast 
option. The tools attach queue pairs to multicast groups while the queue 
pairs are in RESET state. In the IB standard there is no specific definition 
when the attach operation should be processed. In our opinion a QP should not be 
attached until it's in  RTR to receive data from the multicast group.
What is the communitys opinion about that? Is it possible to change the diag tools?

regards Stefan
