Purpose of the inner-eap module

[Graham Clinch]

Hi Folks,

In the standard config there's an second instance of the eap module, 
named 'inner-eap', but it doesn't appear to be referenced anywhere.

I've swapped all occurances of 'eap' in the inner-tunnel site to 
'inner-eap' and now see PEAP/EAP-MSCHAPv2 authentications complete with 
one fewer roundtrip, which feels like an improvement.  Is there a reason 
inner-eap is not used in the default inner-tunnel site?

As an aside, the wiki's EAP module page says "NOTE: There can only be 
one instance of the EAP module." 
(http://wiki.freeradius.org/modules/Rlm_eap), but that doesn't appear to 
be the case here.
