[openib-general] IPoIB CM for merge?

[Pradeep Satyanarayana]

Hello Michael,

Here are a few more observations :

1. For the SRQ case, the skbs and recieve biffers are posted during init 
and even before the rx_qp is created. This causes a problem (atleast for 
non SRQs) for the ehca. We need to call the ipoib_cm_alloc_skb() and 
ipoib_cm_post_recieve() after the rx_qp is in the RTR state.

2. Also found that in ipoib_cm_create_rx_qp() one needs to initialize 
.cap.max_recv_wr and .cap.max_recv_sge. Otherwise this leads to some 
problems like rq overflows and causing communication failures.
