EAX doesn't need a padding mode since for the encryption portion it uses
counter mode. So simply AES/EAX sufficies.

It is not a complete enumeration (since in particular there are quite
a few block ciphers), but see the section "Cipher Filters" in the
reference manual for some description of this.
