Struct TcpSynOptions 

pub struct TcpSynOptions {
    pub mss: Option<u16>,
    pub wscale: Option<u8>,
    pub sack_permitted: bool,
    pub timestamps: bool,
}

Peer TCP options observed on an incoming SYN or SYN-ACK frame.

Captured so the handshake synthesizer can mirror the peer’s negotiated options back in its SYN-ACK response (or record them for later use).

Fields

mss: Option<u16>

Maximum Segment Size advertised by the peer. None if the option was absent (RFC 9293 §3.7.1 says default 536, but we treat absence as “use our default”).

wscale: Option<u8>

Window scale shift count (0–14). None if the peer did not advertise it.

sack_permitted: bool

Whether the peer included SACK-Permitted.

timestamps: bool

Whether the peer included Timestamps. We do not echo these back — both endpoints must send TSopt in their SYN for it to be used (RFC 7323 §3.1), so not echoing disables timestamps cleanly.
