RE: [Xen-devel] wireless card

["James Harper" <james.harper@xxxxxxxxxxxxxxxx>]

I haven't done it under xen. Some (all?) wireless cards have trouble
sending packets with a forged MAC address (something to do with
association to an access point). I think the way it works is that the
MAC address of the wireless client is associated to the AP, and so if
you start sending packets with a different MAC address, the AP is going
to reject them, and if the AP tries to send packets to the MAC of domU,
it won't be able to see it in its list of associated MAC addresses.

At home (no xen, ultrasparcII) I bridge an ethernet adapter to a
wireless card (intersil prism2.5 chipset using hostap driver) which
works fine, but the wireless card is running as an AP so the rules are
reversed.

You may be able to set up an AP to AP bridge (is it called WDS??)
between your xen box and the AP to allow what you want to do.

If you give some more information about your setup I might be able to
offer some other suggestions, eg are you bridging or natting or routing
eth1 to domU (my comments above are based on bridging).
