How to set filters for capturing ethernet raw packets in BPF?

Hi,

I want to send and receive ethernet raw packets using BPF interface. 

The ethernet raw packet frame = destination hardware (MAC) address [6 bytes]+	source hardware (MAC) address [6 bytes]  +
 layer-3 protocol type [2 bytes]  + payload [46 - 1500 bytes] +FCS [4 bytes].

While receiveing, how to set filters for capturing ethernet raw packets only in BPF interface? 

Thanks, 
BVB
