I'm trying to understand how rdma_cm works. More precisely, how it finds
which device (local) and guid/lid (remote) to use.
For the local device if I have understood well:
-Using ip_dev_find, we get an IP (IPoIB or not) device which has a route
to the destination IP.
-We use the first port of the first device which has an IP matching.
For the remote HCA, I can't workout how is the transition done between
the destination IP and the lid.
Can anyone enlighten me?
