    OpenBSD has ported the em(4) driver from FreeBSD. At least on
    OpenBSD, em(4) is partially broken: it fails to receive multicast
    ethernet frames. This effectively breaks both IPv4 and IPv6
    multicast, including IPv6 neighbor discovery.

    I have one report that says FreeBSD 4.9's em(4) has the same bug.
    Can any more people confirm that this breakage exists? In -CURRENT?
    I don't have a FreeBSD box with em(4).
