Yes, it is true that the IEEE 802.1X Authenticator in hostapd is
currently quite tightly integrated with IEEE 802.11 functionality and
cannot be used on wired networks. I would prefer to make it much more
modular in the same way as IEEE 802.1X Supplicant is in wpa_supplicant.
This would make it easier to use the Authenticator functionality with
both other wireless drivers and wired networks. However, I do not know
when I will be able to get enough time to do this.

Open1x project (http://www.open1x.org/) has another open source IEEE
802.1X Authenticator implementation which, I believe, was originally
used on wired networks, so it might be another option for you. However,
it looks like Open1x has been concentrating mostly on the Supplicant
part and the Authenticator code has not been changed at all during last
couple of years.
