I am also experiencing this issue.
I think another way of describing what we may be seeing is that WPA_Supplicant
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 decapsulate
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 netgraph
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 from
the frame if there's a VID of 0.
