Currently, EAPOL Frames in IBSS mode are encrypted if a PTK
is available. This patch turn off encryption for all EAPOL
frames when on IBSS mode, as there is no suitable userspace
calls to configure the control port protocol and settings.
IBSS RSN sort-of worked without this patch because PTKs
are only installed after the completion of a successful
EAPOL exchange, so unicast operations would work, but
multicast and rekeying would often fail.

In addition to my earlier comment about this being totally wrong -- if
you REALLY wanted it, you should probably just add the few API tweaks to
be able to set it from userspace and tweak your userspace.
