This does not seem accurate. The functions are modified to take rdt_domain_hdr
as parameter but then the functions are modified to extract rdt_mon_domain
based on rdt_domain_hdr .... and proceeds to operate on internals of
rdt_mon_domain in a way that contradicts the changelog.

Considering what comes later this seems risky to me to rely on the
code flow to interpret which structure rdt_domain_hdr forms part of. I think
that it will be safer if rdt_domain_hdr gets an identifier that reflects which
structure it forms part of so that the accessors could be made explicit and
have error checking.
