函数名称：从inet6_dev netdevice得到指针

函数原型：static inline struct inet6_dev *in6_dev_get(const struct net_device *dev)

返回类型：struct inet6_dev

参数：

类型参数名称
const struct net_device *dev
354  _read_lock() - mark the beginning of an RCU read-side critical section* When synchronize_rcu() is invoked on one CPU while other CPUs* are within RCU read-side critical sections, then the* synchronize_rcu() is guaranteed to block until after all the other
355  idev等于cu_dereference() - fetch RCU-protected pointer for dereferencing*@p: The pointer to read, prior to dereferencing* This is a simple wrapper around rcu_dereference_check().(ip6_ptr)
356  如果idev则_inc - increment a refcount*@r: the refcount to increment* Similar to atomic_inc(), but will saturate at REFCOUNT_SATURATED and WARN
358  _read_unlock() - marks the end of an RCU read-side critical section.* In most situations, rcu_read_unlock() is immune from deadlock.* However, in kernels built with CONFIG_RCU_BOOST, rcu_read_unlock()
359  返回:idev
