Do you need to have independent authentication on each interface? I have
not tested this type of setup, but you will probably need to add -b<br
ifname> to the command line to get wpa_supplicant to receive the EAPOL
frames from the bridge. I would first try with -ieth0 -bbr0 on the
command line and if that does not work, try running two wpa_supplicant
instances with one using -ieth0 and the other one -ieth1 (both with
-bbr0). It would be interesting to hear whether either of these options
work in this case.
