Description

Feature gate: #![feature(tcp_syncnt)]

This is a tracking issue for bringing a thin wrapper around the Linux's TCP_SYNCNT socket option.

When a client tries to connect to a server but the latter does not respond, the former sends a SYN packet.
How much does the client send to the server before giving up is what the feature is about.

Public API
pub trait TcpStreamExt: Sealed{
  fn syncnt(&self) -> io::Result<u32>;
  fn set_syncnt(&self, count: u32) -> io::Result<()>;
}

Research direction

The issue specifies the TcpStreamExt API and the Linux TCP_SYNCNT socket option, but names no repository files or tests. Start by locating the existing platform-specific TCP socket-option entry points, then verify the getter and setter behavior against Linux; done means the proposed API is implemented as a thin wrapper with coverage for both operations.
