You can have an AP which bridges wifi clients into a LAN:

 wifi-client ))) athn0(AP)-bridge0-em0 -> LAN

Now wifi-client and the LAN can talk on layer 2. I use this at home.

The case where bridging does not work with wireless is where people
are trying to use a bridge to span layer 2 across two APs:

 wifi-client ))) athn0(AP)-bridge0-athn1(client) ))) athn0(AP)-em0 -> LAN

In this case the client cannot reach the LAN on layer 2 because we
don't support the "WDS" extension to IEEE 802.11.

Ah. In that case this shouldn't be an issue.

OK for the diff.
