函数名称：kobject_uevent_net_broadcast

函数原型：static int kobject_uevent_net_broadcast(struct kobject *kobj, struct kobj_uevent_env *env, const char *action_string, const char *devpath)

返回类型：int

参数：

类型参数名称
struct kobject *kobj
struct kobj_uevent_env *env
const char *action_string
const char *devpath
385  ret等于0
389  const struct net * net = NULL
391  ops等于kobj_ns_ops(kobj)
392  如果非ops且设备组指针则
393  ksobj等于设备对象
395  如果(父设备指针 != NULL)则ops等于kobj_ns_ops(父设备指针)
403  如果ops且netlink_ns且namespace则如果type恒等于KOBJ_NS_TYPE_NET则
405  net等于namespace(kobj)
407  如果非net则ret等于uevent_net_broadcast_untagged(env, action_string, devpath)
410  否则ret等于uevent_net_broadcast_tagged(sk, env, action_string, devpath)
415  返回:ret
