[Avila] Problem with wds bridging on avila board

[Tim Harvey]

Joel,

What board are you using?  What are you using for WiFi/WDS (Atheros cards w/
madwifi?).  I assume your setting everything up on the same subnet (bridge) vs
routing?  I do what your talking about all the time both with the IAL and GPL
NPE drivers.

As for the GPL NPE driver, I've had it working on 2.6.18 and 2.6.19 using the
patches at http://trac.nslu2-linux.org/kernel/browser/trunk/patches.  I noticed
that they no longer have the 2.6.18/19 patches there but you should find them
if you go back in their subversion rev's you'll find them.  I have no reason to
believe the patches they have for 2.6.20/21 would give you any compile
problems, I just haven't moved to that kernel.  I never had any compile issues
but I could see issues if your trying to put the driver on other kernels -
there were a few changes that affect the driver between 2.6.18-2.6.21
