socket.AF_PACKET doc: proto is *not* in network byte order

Documentation

The documentation of socket.AF_PACKET says that the value of proto in the address representation must be in network-byte-order:

https://github.com/python/cpython/blame/v3.12.0a3/Doc/library/socket.rst#L196

Value must be in network-byte-order.

This is incorrect. It is true that the corresponding Linux field sll_protocol is in network byte order (see packet(7)), but Python automatically converts to/from host byte order:

https://github.com/python/cpython/blob/v3.12.0a3/Modules/socketmodule.c#L1483

https://github.com/python/cpython/blob/v3.12.0a3/Modules/socketmodule.c#L2104

Note: This applies to addresses passed to socket.bind() and returned from socket.recvfrom(), but does not apply to the proto parameter of socket.socket() -- Python doesn't automatically convert it, so the user must supply a value in network byte order (when using AF_PACKET). It might be a good idea to document this, e.g. the documentation of ETH_P_ALL could mention that it needs to be converted using socket.htons() before passing to socket.socket().

Bonus typo:

https://github.com/python/cpython/blame/v3.12.0a3/Doc/library/socket.rst#L188

The packets are represented by the tuple

"packets" is inaccurate and should be changed to "addresses" or "sockets".

Doc/library/socket.rst の AF_PACKET アドレス表現を開き、バイトオーダーの動作について Modules/socketmodule.c の参照されている箇所を確認してください。bind/recvfrom のアドレスと socket() の proto パラメーターを区別するようにドキュメントを更新し、「packets」という表現を修正してください。ドキュメントに記載された変換と用語が実装と一致すれば完了です。
