31 | * @list: used to maintain a list of currently available transports | |
32 | * @name: the human-readable name of the transport | |
33 | * @maxsize: transport provided maximum packet size | |
34 | * @def: set if this transport should be considered the default | |
35 | * @create: member function to create a new connection on this transport | |

36 | * @close: member function to disconnect and close the transport |
37 | * @rpc: member function to issue a request to the transport | |

39 | * This is the basic API for a transport module which is registered by the | |
40 | * transport module with the 9P core network module and used by the client | |
41 | * to instantiate a new connection on a transport. | |
42 | * | |
8b81ef58 | 43 | * BUGS: the transport module list isn't protected. |
