Hi, all I am a beginner to Linux networking module programming, and I need to write a module which does itself routing algorithm. Is there any method to transmit packet from IP layer; in other words, the packet is built in layer 3 and then sent out, and there's no upper layer involved. If the method is to build my own sk_buff, then how should I fill in other fields in sk_buff besides layer 3 (ex. sk filed...th union..) . Besides, could anyone tell me what the purpose of struct *net_device -> hard_header() ? Thanks your help!
