NAME
       skb_peek - peek at the head of an sk_buff_head

SYNOPSIS
       struct sk_buff * skb_peek(const struct sk_buff_head * list_);

ARGUMENTS
       list_
           list to peek at

DESCRIPTION
       Peek an sk_buff. Unlike most other operations you _MUST_ be careful with this one. A peek
       leaves the buffer on the list and someone else may run off with it. You must hold the
       appropriate locks or have a private queue to do this.

       Returns NULL for an empty list or a pointer to the head element. The reference count is
       not incremented and the reference is therefore volatile. Use with caution.
