Bug Description

I have an onboard network interface, described by lspci as: "Ethernet controller: Sundance Technology Inc / IC Plus Corp IC Plus IP1000 Family Gigabit Ethernet (rev 41)", and use the 'ipg' kernel module (in ubuntu/net/ipg/ inside ubuntu kernel tree). The normal network functionality seems ok, but I found out that avahi-discover wasn't showing other people published services. Looking in Google I also found out that some drivers have buggy support for local multicast as used by Zeroconf.

The workaround is adding to eth0 'stanza' in /etc/network/interfaces "pre-up ifconfig eth0 allmulti", to 'force' the interface process all multicast packets. Even the solution make everything work fine, I think some investigation in the module code would be good to check if something is wrong/unimplemented there.

I recently upgraded to Feisty, but the problem (not seeing other people's services) was in my old Edgy, too.
