wpa_supplicant with madwifi using bridge

Jouni,

Can you explain this statement?

"Though, it should still be kept in mind that IEEE 802.11
is allowing clients to send out frames only with their own address as
the source address so normal layer 2 bridging does not work for data
frames."

How does wpa_supplicant work when the interface is part of the bridge?  Can
it still act transparent, or only as a proxy/arp?

Thanks,

Joel

Updating to 0.5.7 would be the easiest solution for this, but if this is
not feasible for some reason, you could try to backport the support for
-b argument, i.e., the following two changes, into 0.5.x:
