Hi ,
I wanted to know how do I use eth0 from kernel space. How do i get the
information of running struct net_device references??
I wanted to capture the stats on eth0 from kernel space.
You can access all "net_dev"s in the kernel by using the macro for_each_netdev or any of its variants if thats what you intended to ask.
The following variants of for_each_netdev macros is defined in include/linux/netdevice.h in the kernel source tree
1226#define for_each_netdev(net, d) \
1227 list_for_each_entry(d, &(net)->dev_base_head, dev_list) 1228#define for_each_netdev_reverse(net, d) \ 1229 list_for_each_entry_reverse(d, &(net)->dev_base_head, dev_list) 1230#define for_each_netdev_rcu(net, d) \ 1231 list_for_each_entry_rcu(d, &(net)->dev_base_head, dev_list) 1232#define for_each_netdev_safe(net, d, n) \ 1233 list_for_each_entry_safe(d, n, &(net)->dev_base_head, dev_list) 1234#define for_each_netdev_continue(net, d) \ 1235 list_for_each_entry_continue(d, &(net)->dev_base_head, dev_list) 1236#define for_each_netdev_continue_rcu(net, d) \
