[ewg] Automated Port Migration on RC connected QPs

[Rupert Dance]

Hi Sean,

One of our developers created a code example to do APM between ports on an
HCA. This code is available in Section 8.1 of the Mellanox RDMA Aware
Programming User Manual which is available here:

er_manual.pdf

Thanks

Rupert

The RDMA CM does not support APM.  You could use the RDMA CM to connect, but
would need to exchange alternate path information in band and modify the QP
directly to set the alternate path information and APM state.
