After adding some detailed error, we see that TestListenMulticastUDP is failing because addmulti mixes IPv4 and IPv6:

udpsock_plan9_test.go:39: multicast not working on plan9: listen udp4 224.0.0.254:0: addmulti fe80::5054:ff:fe12:3456/64: write /net/udp/clone: incompatible multicast/interface ip address

Also, only in 9legacy, announce doesn't like the multicast address:

udpsock_plan9_test.go:39: multicast not working on plan9: listen udp4 224.0.0.254:0: announce udp4 224.0.0.254:0: not a local IP address

I have a CL I'll send out soon.

@gopherbot, please add labels OS-Plan9, Testing, NeedsFix
