A few TCP socket options have been added to the Linux kernel these last few years. This commit adds all the ones available in Linux 6.0: https://elixir.bootlin.com/linux/v6.0/source/include/uapi/linux/tcp.h#L91 While at it, the TCP_FASTOPEN option has been moved lower in the list just to keep the same order as in tcp.h to ease future synchronisations. Please note that I initially wanted to get socket.TCP_FASTOPEN_CONNECT. I was going to add only this one but while at it, here are all the missing ones.

Feature or enhancement
socketmodules already know most TCP socket options (TCP_NODELAY,TCP_MAXSEG,TCP_CORK, etc.) but not the recent ones.Here is the complete list from the last Linux kernel version:

Pitch
I noticed
TCP_FASTOPEN_CONNECTwas missing. I wanted to use it to write some quick tests for the kernel (MPTCP development). I was going to add only this one but while at it, best to add all the missing ones.Linked PRs
