* struct p9_trans_module - transport module interface

* @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
* @pref: Preferences of this transport
35
* @def: set if this transport should be considered the default
36
* @create: member function to create a new connection on this transport

38
* @request: member function to issue a request to the transport
39
* @cancel: member function to cancel a request (if it hasn't been sent)
41
* This is the basic API for a transport module which is registered by the
42
* transport module with the 9P core network module and used by the client
43
* to instantiate a new connection on a transport.
45
* The transport module list is protected by v9fs_trans_lock.
