Subject: [PATCH 2.6.14-rc3] sis190.c: fix multicast MAC filter

Hi,

Here is a patch that changes the way the MAC filter is computed for the
multicast addresses. The computation is taken from the SiS GPL driver.

This patch is necessary to get IPv6 working.

Thanks,
Aurelien

Ok.

May I assume that it has been tested on the usual k8s-mx ?

If so, feel free to forward to [email protected] and [email protected].
I've just bought a mobo to test this adapter but it will not be ready before
this week end.
