This is just a note to say that I *have* observed problems with multicast setup in fxp(4) -- it seems to need setting up of the link-layer hash filter for a group to transmit as well as receive. This isn't OK, NICs should be able to transmit w/o receive setup, and may break normal use-cases (esp. IPv6), I posted to freebsd-net@ about this over the past 12 months, but did not have time to reproduce or isolate the issue. So a fix is very, very welcome. Thanks for working on this. I have an fxp(4) but it's in my home server RELENG_7 box... any plans to backport? thanks, BMS
