Can you let me know how to reproduce the panic?

1. linux upstream<   ----rping---->   linux upstream?

rdma_client on v5.13<   --->   rdma_server on upstream kernel.

2. just run rping?

Running rdma_client on v5.13 and rdma_server on upstream can reproduce
the issue.

Note: running rping can reproduce the issue as well.

rping and rdma_server/rdma_client are from the latest rdma-core?

Yes, use the latest rdma-core from
https://github.com/linux-rdma/rdma-core (master branch).

Latest kernel + latest rdma-core < ------rping---- > 5.10.y stable +
latest rdma-core
Latest kernel + latest rdma-core < ------rping---- > 5.11.y stable +
latest rdma-core
Latest kernel + latest rdma-core < ------rping---- > 5.12.y stable +
latest rdma-core
Latest kernel + latest rdma-core < ------rping---- > 5.13.y stable +
latest rdma-core

The above works well.
