Subject
IPoIB multicast





Can some one please explain the details of the IPoIB multicast. Or if 
there is some previous discussion or documentation about that can I get a 
pointer? 

In particular I am looking to understand the details of  initiation of 
multicast join throug ipoib_send() and the join completion appears to 
happen through a MAD callback. How are the corresponding skbs freed? Why 
is the tx_ring used for send and what is the mcast->pkt_queue used for. 
Thanks for all the help.
