LinuxQuestions.org - How to specify ether type with raw socket

Hello,
I'm trying to specify ether type when opening a raw socket. I've already done it under Windows and MacOSX but dunno how to do it under Linux.
Under MacOSX, I'm using:

Code:

struct ndrv_protocol_desc desc;

struct ndrv_demux_desc demux_desc[1];



/*... some code to create the socket and bind the socket to the selected network interface ...*/



bzero(&desc, sizeof(desc));

bzero(&demux_desc, sizeof(demux_desc));



desc.version = NDRV_PROTOCOL_DESC_VERS;

desc.protocol_family = NDRV_DEMUXTYPE_ETHERTYPE;

desc.demux_count = (u_int32_t)1;

desc.demux_list = (struct ndrv_demux_desc*)&demux_desc;



demux_desc[0].type = NDRV_DEMUXTYPE_ETHERTYPE;

demux_desc[0].length = sizeof(demux_desc[0].data.ether_type);

demux_desc[0].data.ether_type = MY_ETHER_TYPE;

if (setsockopt( fd, SOL_NDRVPROTO, NDRV_SETDMXSPEC, (caddr_t)&desc, sizeof(desc))) {

  /*failed, perform some cleanup and leave function*/

}

/*succeed, get mac address and other stuff then leave function*/

What would be the equivalent under Linux ?

Thanks,
