Revert "Docs/zh_CN: Translate skbuff.rst to Simplified Chinese" 



This reverts commit d3e7609c6e5ec92587ed1043a985749d22cc78d1.
The commit cause a warning:
  Documentation/networking/skbuff.rst:34: WARNING: duplicate label crc, other instance in Documentation/translations/zh_CN/networking/skbuff.rst

And there's no simple way to keep the meaningful doc context and avoid the
warning, so, let's remove the doc.

struct sk_buff

==============



:c:type:`sk_buff` 是表示数据包的主要网络结构体。



基本sk_buff几何结构

-------------------



.. kernel-doc:: include/linux/skbuff.h

   :doc: Basic sk_buff geometry



共享skb和skb克隆

----------------



:c:member:`sk_buff.users` 是一个简单的引用计数，允许

多个实体保持 struct sk_buff 存活。 ``sk_buff.users != 1``

的 skb 被称为共享 skb（参见 skb_shared()）。



skb_clone() 允许快速复制 skb。不会复制任何数据缓冲区，

但调用者会获得一个新的元数据结构体（struct sk_buff）。

&skb_shared_info.refcount 表示指向同一数据包数据的

skb 数量（即克隆）。



数据引用和无头skb

-----------------



.. kernel-doc:: include/linux/skbuff.h

   :doc: dataref and headerless skbs



校验和信息

----------



.. kernel-doc:: include/linux/skbuff.h

   :doc: skb checksums
