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
