RAW ethernet in kernel space

[Patrick Rittiner]

hi everyone,

I have a problem, I would like to open a ethernet socket and receive  
all data (RAW ethernet) on the ethernet interface on it. ( interface  
has to be in promisc mode ) In user space this is not a big problem,  
but how can I do it in kernel space? I mean, i can not use functions  
like ioctl() and socket(), right? so I think there is a sock_create().

so how can I write code like this for kernel space:

	memset(&ifInfo, 0x00, sizeof(ifInfo));
	strncpy(ifInfo.ifr_name, iface,  IFNAMSIZ);
	ioctl(sock, SIOCGIFFLAGS, &ifInfo);
	ifInfo.ifr_flags |= IFF_PROMISC;
	ioctl(sock, SIOCSIFFLAGS, &ifInfo);

thanks for your help
