  You can edit mods-available/eap:

eap {
	...

	dedup_key = "%{Calling-Station-Id}"

}

  When the supplicant starts a new EAP session, the server will delete old sessions for that Calling-Station-Id.

  If the supplicant is *really* doing multiple EAP sessions, well, most of them will fail.  But in the general case, the supplicant is only doing multiple EAP sessions when it's misbehaving.

  It's compile-tested.  So it it works, great.  If not, we're happy to accept patches or bug reports.
