Hello, I'm currently developing a packet filter, and I noticed that GNU Mach doesn't catch Ethernet multicast packets (though broadcast packets are correctly handled). I temporarily set mc_filter[0] and mc_filter[1] to 0xffffffff (as it is done for promiscuous mode) in driver rtl8139, and then multicast works. My problem is that I'd like to know if there is a generic solution to enable multicast support by default on all drivers which support it.
