The goal is not to have a hard dependency between the RDMA driver and
the ethernet driver.  One day, there may be a newer ethernet driver
for newer devices.  The RDMA driver may be the same because it
operates at a higher level.  The hard dependency will require the
older ethernet driver to always be loaded even if it is not needed.
