This just emphasizes why we need to converge to a single method.

In my opinion, we already have it.

For local registrations, ib_reg_phys_mr()/ib_get_dma_mr(). These are not
quite equivalent, btw.

For remote registrations, ib_post_send(FRMR).

Unfortunately, there exist ancient adapters in-tree that don't support
FRMR, and some ULPs have attempted to work on them. That's why the
situation is confusing.
