  If the MAC is in the User-Name attribute, then you're using authenticating by User-Name.  FreeRADIUS doesn't care what's *in* the User-Name.

  How do you give them that option?

  Is the User-Name in the access-Request packet?

  You want to do "something".  But you don't know what's in the packets, and you don't really know what you want to do.

  So the question is impossible to answer until there's some more detailed information.
