|
* enum net_device_flags - &struct net_device flags
|
|
*
|
|
* These are the &struct net_device flags, they can be set by drivers, the
|
|
* kernel and some can be triggered by userspace. Userspace can query and
|
|
* set these flags using userspace utilities but there is also a sysfs
|
|
* entry available for all dev flags which can be queried and set. These flags
|
|
* are shared for all types of net_devices. The sysfs entries are available
|
|
* via /sys/class/net/<dev>/flags. Flags which can be toggled through sysfs
|
|
* are annotated below, note that only a few flags can be toggled and some
|
|
* other flags are always preserved from the original net_device flags
|
|
* even if you try to set them via sysfs. Flags which are always preserved
|
|
* are kept under the flag grouping @IFF_VOLATILE. Flags which are volatile
|
|
* are annotated below as such.
|
|
*
|
|
* You should have a pretty good reason to be extending these flags.
|
|
*
|
|
* @IFF_UP: interface is up. Can be toggled through sysfs.
|
|
* @IFF_BROADCAST: broadcast address valid. Volatile.
|
|
* @IFF_DEBUG: turn on debugging. Can be toggled through sysfs.
|
|
* @IFF_LOOPBACK: is a loopback net. Volatile.
|
|
* @IFF_POINTOPOINT: interface is has p-p link. Volatile.
|
|
* @IFF_NOTRAILERS: avoid use of trailers. Can be toggled through sysfs.
|
|
* Volatile.
|
|
* @IFF_RUNNING: interface RFC2863 OPER_UP. Volatile.
|
|
* @IFF_NOARP: no ARP protocol. Can be toggled through sysfs. Volatile.
|
|
* @IFF_PROMISC: receive all packets. Can be toggled through sysfs.
|
|
* @IFF_ALLMULTI: receive all multicast packets. Can be toggled through
|
|
* sysfs.
|
|
* @IFF_MASTER: master of a load balancer. Volatile.
|
|
* @IFF_SLAVE: slave of a load balancer. Volatile.
|
|
* @IFF_MULTICAST: Supports multicast. Can be toggled through sysfs.
|
|
* @IFF_PORTSEL: can set media type. Can be toggled through sysfs.
|
|
* @IFF_AUTOMEDIA: auto media select active. Can be toggled through sysfs.
|
|
* @IFF_DYNAMIC: dialup device with changing addresses. Can be toggled
|
|
* through sysfs.
|
|
* @IFF_LOWER_UP: driver signals L1 up. Volatile.
|
|
* @IFF_DORMANT: driver signals dormant. Volatile.
|
|
* @IFF_ECHO: echo sent packets. Volatile.
