From: Leon Romanovsky <leonro@nvidia.com>

Starting from the commit 66920e1b2586 ("rdma_rxe: Use netlink messages
to add/delete links") from the 2019, the RXE modules parameters are marked
as deprecated in favour of rdmatool. So remove the kernel code too.

Do you mean that rxe_cfg tool can not be used again?
