dear kernel brothers,
i am asking one doubt regarding N/W DEVICE DRIVERERS in this mail.
my program is
#define MODULE
#include <linux/module.h>
#include <linux/kernel.h>
#include <linux/socket.h>
#include <linux/skbuff.h>
#include <linux/netdevice.h>
int init_module(void)
{
printk("<1>hello world");
return 0;
{
void cleanup_module(void)
{
printk("<1>good bye cruel world");
}
int netif_rx(struct sk_buff *skb)
{
printk("i am using and testing of dev.c");
return NET_RX_DROP;
}
ACTUALLY, I need to use netif_rx to print out the ethernet frame
format.but after compiling this program, i am getting only the output
of helloworld for inserting the module and goodbye cruel world while
removing the module .
but i am not getting "i am using and testing of dev.c
actully, i need ouput is
"print ethernet frame format in bytes"
i compiled the program by using cc -I /usr/src/linux-2.4.20-8/include
-Wall -c filename.c does there anywrong in this complation
procedure...
so please help me and thanks in advance....
atcual project : i i have to write drivers in RTLINUX for ETHERNET CARD".
step1: print the ethernet frame format by using netof_rx or any other
which are relateds to n/w drivers.thers is dev.c
which is in linux/core/net/dev.c .netif_rx using netif_rx. i have to
include <linux/socket.h> , skbuff.h, netdevice.h also for this.
but i am getting segmentation fault sometimes
so what is the wrong in my program ?i am not understanding.
help me and thanks in advance..........
