Something to think about:
Do we need to explicitly support all the different EAP types?
Instead could we have a generic 'catch all' type that hides the details of the packet. For example Chewie only really requires the identity, and maybe message ids, so the rest can be classified as extra data.
So in theory we could have EAPFailure, EAPSuccess, EAPIdentity, EAPGeneric.
Instead of EAPFailure, EAPSuccess, EAPIdentity, EAPGeneric, EAPTLS, EAPTTLS, EAPLegacyNAK, EAPMD5....
I don't see why Chewie actually needs to care about the specific EAP type, it's passed through to the RADIUS server anyway. - could still parse the type field to report that.
Pros:
- Simplifies the implementation.
- Hopefully all EAP types will be supported.
Cons:
- Won't be able to access some fields. (but do we even need to)
