--- Comment #14 from topsecretsauce <xerowingsx9k@gmail.com> ---
I am also experiencing this issue.

I think another way of describing what we may be seeing is that WPA_Supplic=
ant
may be unable to process requests tagged with VID 0. This may be similar to=
 how
dhclient was unable to do so until Franco worked on having dhclient decapsu=
late
VID 0. I am using a netgraph configuration on 13.1 that filters out 802.1Q
information if it contains VID 0 and from looking at the CAP for that netgr=
aph
interface, it appears to respond to EAP Identity requests normally. And like
the others, if I simply use WPA_Supplicant with the physical interface and =
let
it receive the VID 0 EAP identity request traffic, it doesn't respond to the
identity requests.

What we may need is for WPA_Supplicant to decapsulate 802.1Q information fr=
om
the frame if there's a VID of 0.
