[ofa-general] Loopback connection not working on Chelsio

[pandit ib]

Hi,

I'm having trouble getting loopback rdma connections working on Chelsio.

We were told that loopback connections are not supported.

Is this an iWarp or Chelsio specific issue?

What are the issues that is preventing it from working?

Are there plans for supporting this capability?

In our platform, clients and servers could be running on the same node
and they talk to each other via rdma channels.

Btw, here is the error with rping in loopback mode. Our application is
getting the same error.
