Hello,
This post has some relavance to a former question , which dealt with getting
the ip of eth0 ;Now I must also get the IP on eth0:1 .
I do have an IP on both eth0 and eth0:1 , as running ifconfig shows
I try in init method of a module I wrote:
.........
struct net_device* device;
device = dev_get_by_name("eth0:1");
if (device == NULL)
{
printk("device is NULL\n");
}
...
I do get the "device is NULL message" after insmod my module.
I had looked at net/pv4/devinet.c in dev_get_by_name() implementation:
struct net_device *dev_get_by_name(const char *name)
{
struct net_device *dev;
read_lock(&dev_base_lock);
dev = __dev_get_by_name(name);
if (dev)
dev_hold(dev);
read_unlock(&dev_base_lock);
return dev;
}
but I don't know what the problem is.
Any idea how can I get the device for eth0:1?
Regards,
Amir
