* Add TCP keep alive idle setting * Add TCP keep alive idle setting: auto generated * Add TCP keep alive support in Linux * Add TCP keep alive support in MacOS, FreeBSD * Add TCP keep alive support in Windows * fix bug introduced in adding tcp keep alive adjustment * embed macOS const to avoid platform inconsistency * embed macOS const to avoid platform inconsistency(again) * add TCP Keep Alive support in config * use sys/unix instead of syscall Suggestion from: https://github.com/v2fly/v2ray-core/pull/1395#issuecomment-974761647 * use sys/unix instead of syscall Suggestion from: https://github.com/v2fly/v2ray-core/pull/1395#issuecomment-974761647 * Separate TcpKeepAliveIdle and TcpKeepAliveInterval check logic * Disable tcp keepAlive when TcpKeepAliveIdle < 0 and TcpKeepAliveInterval <= 0 Co-authored-by: xqzr <34030394+xqzr@users.noreply.github.com> Co-authored-by: ValdikSS <iam@valdikss.org.ru> Co-authored-by: Shelikhoo <xiaokangwang@outlook.com> Co-authored-by: xqzr <34030394+xqzr@users.noreply.github.com>
