libnet_adv_write_link() On OS X

All,

I am trying to write a wire ready layer 2 frame by passing it to libnet_adv_write_link(). I am passing it in the correct libnet handle and the correct memory location. The size of the frame as caught by pcap in the pcap_pkthdr is 1518 bytes. This makes sense a 1500 byte IP packet in a 18 byte frame.

I am basically capturing with pcap and then turning around and sending out the packet using libnet. Libnet_adv_write_link complains that the packet is too long. So long as my length is less than 1500 then it doesn't complain. Any ideas?
