Re: D-Link DFE580-TX (ste*) woes

FWFW, I seem to have (finally) gotten the DFE580-TX to work better
(when it comes to multicast reception) by applying the following (very
ugly) patch (against 3.1-RELEASE, as it happens):

This patch does NOT AT ALL, I think, Do The Right Thing[tm].  It does,
however, make things Work For Me[tm], which is better than nothing.

I'd welcome suggestions on how to improve the code -- the patch above
should make the kernel always receive all IP multicast packets
regardless of the number of actual multicast listeners, which is *not*
a good idea if there's a lot of multicast flowing around your network.
(On my network, the only multicast is OSPF, and I definitely want to
receive that.)

Any reports about the multicast filter working (or not) with the
DFE-550TX?
