Stub out support for TCP_MAXSEG. Adds support to set/get the TCP_MAXSEG value but does not really change the segment sizes emitted by netstack or alter the MSS advertised by the endpoint. This is currently being added only to unblock iperf3 on gVisor. Plumbing this correctly requires a bit more work which will come in separate CLs. PiperOrigin-RevId: 257859112
Netstack is a network stack written in Go.
Try it out on Linux by installing the tun_tcp_echo demo:
go install github.com/google/netstack/tcpip/sample/tun_tcp_echo
Create a TUN device with:
[sudo] ip tuntap add user <username> mode tun <device-name> [sudo] ip link set <device-name> up [sudo] ip addr add <ipv4-address>/<mask-length> dev <device-name>
Then run with:
tun_tcp_echo <device-name> <ipv4-address> <port>
Please see CONTRIBUTING.md for more details.
