Yes.

That is not the exact truth.. If you would like to use AP mode, you
would most probably need the special firmware. However, if you just want
to make a point-to-point link between two WaveLAN cards and, e.g.,
bridge two ethernet networks over this link, you could use WDS mode for
this. Current Host AP driver has support for this mode as 'iwconfig
wlan0 mode Repeater' (not really the best name for the mode, but anyway,
this is the WDS mode). If I remember correctly, this mode worked fine
with Prism2, Lucent/Orinoco/Agere, and Symbol -based cards.

In WDS mode you will need to setup p-t-p link between two cards (iwpriv
wlan0 wds_add <hwaddr>) and use wlan#wds# interfaces in the bridge
setup. This way you should be able to use Linux bridge code also with
WaveLAN cards. The WDS frames have four addresses and the transmitter
can thus use its own address since there is a separate address field for
the "original source".
