MS-MPPE-{Send,Recv}-Key attributes are not really used with STA with any
method; they are just used to pass some information (session key) from
the EAP authentication to the Authenticator. Anyway, you are correct in
that those are not send with EAP-MD5 (since it does not generate such
session key).

Well.. You can't. In order to send a key to STA, AP needs some kind of
shared secret with STA. With IEEE 802.1X this is the session key
provided by some EAP types, like EAP-TLS.
