If required, the trailer should be added by your ethernet driver.

When I build an igmp message with

libnet_build_igmp
libnet_build_ipv4
libnet_build_ethernet

The packet is really smaller than the minimum ethernet frame (46 data bytes). If I try to add the trailer at the ethernet layer (so it is 64 bytes) it wipes out the packet, is it possible to have an offset in build_ethernet so the trailer is added after the IP datagram ?
