[patch] ATL1E nic driver don't support multicast

[Daniel Nyström]

After installing my new ASUS motherboard Avahi stopped working. It
turned out that the ATL1E driver failed receiving multicasts.

I applied the following patch, and it started working immediately. As
ASUS is one of the bigger motherboard vendors I think this might be
important to get into a new kernel version.
