[PATCH rfc 0/3] nvmet-rdma automatic port re-activation

[Sagi Grimberg]

When a RDMA device goes away we must destroy all it's associated
RDMA resources. RDMa device resets also manifest as device removal
events and a short while after they come back. We want to re-activate
a port listener on this RDMA device when it comes back in to the system.

In order to make it happen, we save the RDMA device node_guid on a
ULP listener representation (nvmet_rdma_port) and when a RDMA device
comes into the system, we check if there is a listener port that needs
to be re-activated.

In addition, reflect the port state to the sysadmin.
