Hi,
I would like to check the interface status (up/down) within linux kernel. Is there any routine (sort of ioctl) to do this. Any code that is already in use in kernel would also be helpful for me. Please let me know.
I think netif_carrier_ok() could help. You can refer network driver code(e.g. e1000_main.c). -- Thanks, Nilesh
