retransmit

Resending network data that got lost, so the receiver eventually gets a complete, correct stream.

TCP guarantees delivery, which means when a packet goes missing the sender must send it again — that resend is a retransmit. It's a core part of what makes TCP reliable despite an unreliable network underneath. Here it's noted as not-yet-implemented, so the networking stack doesn't yet recover lost packets on its own.
