These are distinct from old-school LEAP (ie, Network EAP) in that
they are standard Dynamic WEP with LEAP as an EAP method and use
open-system authentication. Old LEAP uses the non-standard LEAP
authentication algorithm. The config for each is different and thus
we need to make sure we handle both cases.
Some adjustments need to be made to read and write secret flags, and
to ensure that connections that don't have system-owned secrets are
still parsed as expected. testcases for 802.1x connections to come
shortly.
