The type representing the internal state of the IPv6 stack.

Disconnect from the IPv6 stack. While this might take some time to complete, it can never result in an error.

udp t obtains a descriptor for use with the UDPV6 module, usually to transmit traffic.

tcp t obtains a descriptor for use with the TCPV6 module, usually to initiate outgoing connections.

ip t obtains a descriptor for use with the IPV6 module, which can handle raw IPv6 frames, or manipulate IP address configuration on the stack interface.

listen_udp t ~port cb registers the cb callback on the UDPv6 port and immediately return. If port is invalid (not between 0 and 65535 inclusive), it raises Invalid_argument. Multiple bindings to the same port will overwrite previous bindings, so callbacks will not chain if ports clash.

• deprecated use UDP.listen instead (since mirage-protocols 6.0.0).

listen_tcp ~keepalive t ~port cb registers the cb callback on the TCPv6 port and immediately return. If port is invalid (not between 0 and 65535 inclusive), it raises Invalid_argument. Multiple bindings to the same port will overwrite previous bindings, so callbacks will not chain if ports clash. If ~keepalive is provided then these keepalive settings will be applied to the accepted connections before the callback is called.

• deprecated use TCP.listen instead (since mirage-protocols 6.0.0).

listen t requests that the stack listen for traffic on the network interface associated with the stack, and demultiplex traffic to the appropriate callbacks.
