Ethernet IP multicast maximum packet size

Hello developers,

I googled around all day, but did not find any satisfying answer. Is
there a maximum packet size when I use IP multicasting in a local
ethernet LAN? Or more precisely, does the multicast code in Linux
handle an IP fragmentation/defragmentation of a 63K UDP multicast
datagram, which is transmitted over an 1500bytes MTU ethernet? Or
should I stay on the safe edge and don't construct datagrams > 1500 so
I'll avoid fragmentation?
