The weird thing about this is that equipment varies dramatically in how
it handles this.
For example, the now-ancient 3Com 4400s handled this very well indeed;
they treated non-EAP traffic as macauth, until the first EAP packet from
a given source MAC, at which point they toggled a soft-state bit, making
that MAC/port combo "EAP required", and clearing the state at link-down.
Worked very well.
Juniper handle this poorly - if you force macauth-only they macauth
straight away, otherwise you wait NxM (N=configurable, M=EAP timeout)
which is almost always longer than you want to wait for DHCP to complete
on a non-EAP device :o/
