Subject: [PATCH 2.6.14-rc3] sis190.c: fix multicast MAC filter
Date: Wed, 5 Oct 2005 22:33:50 +0200	[thread overview]
Message-ID: <20051005203350.GA3096@farad.aurel32.net> (raw)

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
