[RFC PATCH v5 05/27] nvme-tcp-offload: Add controller level error recovery implementation

[Sagi Grimberg]

> In this patch, we implement controller level error handling and recovery.
> Upon an error discovered by the ULP or reset controller initiated by the
> nvme-core (using reset_ctrl workqueue), the ULP will initiate a controller
> recovery which includes teardown and re-connect of all queues.

It's becoming an eye-soar how much our transports duplicate code...
