[Bridge] Hardware requirements for bridging wired+wireless together

[Umar Qureshey]

Hi,

I have been trolling the 'net as well as the archives of this list for
quite a while now.

I am still unclear on the requirements for getting an Ethernet and
Wireless interface to bridge together.

Currently, I am working with an esoteric radio that only supports Ad-Hoc
and Managed modes.  There seemingly is not support for WDS (Wireless
Distribution System) on this radio.

I have been trying to bridge my eth0 and wlan0 but it doesn't seem to
work.  Currently, my commands to get the bridge up are:

ifconfig eth0 0.0.0.0
ifconfig wlan0 0.0.0.0
brctl addbr br0
brctl addif br0 eth0
brctl setfd br0 1           #BusyBox version of brctl doesn't take 0 as
a time parameter so I change it to 1 (sec)
ifconfig br0 up
wpa_supplicant -Dwext -iwlan0 -bbr0 -c/root/wpa_supplicant.conf

Then I try to run udhcpc (DHCP client) on the bridge hoping to get DHCP
from the AP/router:

# udhcpc -ibr0 -b
udhcpc (v1.15.2) started
Sending discover...
Sending discover...
Sending discover...
No lease, forking to background

What I'd like to inquire is that is WDS support in the firmware/hardware
of the radio required to bridge eth0 and wlan0?
Any other tips to get the above interfaces to successfully bridge
together would be great.

Thanks,
Umar
