But the Linux CM code doesn't always create the reverse CM MAD from

Spec citation for this is:

I can't quickly find a link, but I believe all CM MADs are reversible, per the
spec.

When IP based addressing was introduced, ib_create_ah_from_wc was
changed in order to support a suitable AH. Since this AH should
now contains the DMAC (which isn't a simple derivative of the GID).
In order to find the DMAC, an ARP should sometime be sent. This ARP
is a sleeping context.
