IIRC in C++ an enum can be lowered into an int. Have you tried to declare
wantedDivider as an SPIClockDivider? See also this:

It is possible that there is no very nice solution.

Please go ahead. We'll see then if we integrate that to the CoAP library (see
the WIP coap implementation) or have it as a separate library. Please don't
name it as "Ethernet", however, as that is the Arduino Ethernet (really TCP and
UDP) library.
