[openib-general] Alternate Path Migration support?

[fabbri]

Hi,

I am looking at using Alternate Path Migration (APM) to do failover of a
Reliable Connection (RC).

A couple of questions:

1. Does the openib stack on tavor H/W support APM?   Anyone played with it?

2. Do I need to supply the alternate path in the ib_cm_connect, or can I later
do a ib_qp_modify to supply the alternate path?  

If ib_qp_modify is sufficient, should this cause the LAP CM message to be sent,
or is that something that the consumer has request separately (after the call to
qp_modify)? 


Thanks, 

Aaron
