I bet it doesn't drop traffic from *all* link-local addresses, just ones that it doesn't expect. <consults crystal ball because you didn't include a dmesg> If you are on a release that enables SOII, you can try disabling it with "ifconfig <interface> -soii", or upgrade to 6.6 where SOII is no longer used for link-local addresses. Also, if you are using autoconf rather than hard-coding, you'll probably need to disable autoconfprivacy.
