Is RDMA (iWARP) supported in LXC?

So I’m building a server that will run Proxmox on the host, which has full support for LXC containers. I want to test and run RDMA applications through iWARP, using the Chelsio NICs I have. The LXC will run Debian 10 (just like host) and the kernel is version 5.4.14.

Is RDMA is fully supported in LXC containers?
If so, should it be a privileged container for it to work or can it also work with unprivileged containers?
What are the setup requirements in order for it to work?
