/**
* struct p9_trans_module - transport module interface
* @list: used to maintain a list of currently available transports
* @name: the human-readable name of the transport
* @maxsize: transport provided maximum packet size
+ * @pooled_rbuffers: currently only set for RDMA transport which pulls the
+ * response buffers from a shared pool, and accordingly
+ * we're less flexible when choosing the response message
+ * size in this case
* @def: set if this transport should be considered the default
+ * @supports_vmalloc: set if this transport can work with vmalloc'd buffers
+ * (non-physically contiguous memory). Transports requiring
+ * DMA should leave this as false.
* @create: member function to create a new connection on this transport
* @close: member function to discard a connection on this transport
* @request: member function to issue a request to the transport
