[PATCH rdma-next 0/3] Add net namespace awareness to device registration

[Leon Romanovsky <leon@kernel.org>]

From Mark:
Introduces net namespace awareness to RDMA device registration and update
relevant users accordingly.

Currently, RDMA devices are always registered in the initial network namespace,
for example even when their associated devlink devices have been moved to
a different namespace via devlink reload.

This results in inconsistent behavior and namespace mismatches.

So in this series, we update the RDMA core to optionally accept
a net namespace during device allocation, allowing drivers to associate
the RDMA device with the correct namespace. In addition, we ensures that
IPoIB inherit the namespace from the underlying RDMA device, maintaining
consistency across the RDMA stack.

Thanks

  RDMA/core: Extend RDMA device registration to be net namespace aware
  RDMA/mlx5: Allocate IB device with net namespace supplied from core
    dev
  RDMA/ipoib: Use parent rdma device net namespace
