So, I think that our old-transport below is just fine.
No need to change it (and you aren't, since it is currently
implemented
as a function).
I think there is a need to change this. Encoding the transport into

Depends on who is we.
For ULPs, you are probably right.
However, core services (e.g., mad management, CM, SA) do care about
various details.
In some cases, where it doesn't matter, this code will use management
helpers.

We don't want to stop code branches that are not abstractions but rather
depend
on the specific technology!
There is no generic iWARP CM - only one.
