Detailed Description

Link info operations.

Field Documentation

int(* rtnl_link_info_ops::io_alloc)(struct rtnl_link *)

Called to assign an info type to a link.

Has to allocate enough resources to hold attributes. Can use link->l_info to store a pointer.

Referenced by rtnl_link_set_info_type().

int(* rtnl_link_info_ops::io_clone)(struct rtnl_link *, struct rtnl_link *)

Called when a link object is cloned.

Must clone all info type specific attributes.

void(* rtnl_link_info_ops::io_dump[NL_DUMP_MAX+1])(struct rtnl_link *, struct nl_dump_params *)

Called when the link object is dumped.

Must dump the info type specific attributes.

void(* rtnl_link_info_ops::io_free)(struct rtnl_link *)

Called to release all resources previously allocated in either io_alloc() or io_parse().

char* rtnl_link_info_ops::io_name

Name of operations, must match name on kernel side.

int(* rtnl_link_info_ops::io_parse)(struct rtnl_link *, struct nlattr *, struct nlattr *)

Called to parse the link info attribute.

Must parse the attribute and assign all values to the link.

int(* rtnl_link_info_ops::io_put_attrs)(struct nl_msg *, struct rtnl_link *)

Called when construction a link netlink message.

Must append all info type specific attributes to the message.
